INTRODUCTION
The Prospector, Thermoelectric Alloy Sorter (TEAS) uses a theory like that of a thermocouple,
involving the direct conversion of temperature differences into electricity. This principle is also
known as the Seebeck Effect. A thermocouple type circuit is formed when a heated metal
probe makes contact with an unheated test metal. The thermal connection of these two
junctions, one at an elevated temperature and the other at room temperature, generates a
small voltage. The voltage varies with the type of test metal and can be consistently correlated.
The energy produced is displayed numerically on the liquid crystal display as a TE-Reading.
This thermal electric property of metals and temperature can be used to characterize most
types of metal. Industrial quality control instruments use this as a method to identify metal
alloys. This process known as thermoelectric alloy sorting.
http://en.wikipedia.org/wiki/Thermoelectric effect. This widely-known and approved method
(ASTM E977), is used for metal classification and verification. This instrument is also cited in
the RB211-72-AG183 for aircraft use.
APPLICATIONS

INSTRUCTIONS
Video instruction available:
http://koslow.com/metal_test_kits/ThermoElectric_Alloy_Sorter?cPath=1
1. Remove protective plastic boot from the metallic hot probe tip.
2. Plug the TEAS into 110 Volt AC line power.
3. Connect the Cold Circuit. Either the Alligator Clip, The Wand or Block to
the BNC connector on the bottom side of the instrument. The BNC fitting
requires pushing and twisting.
4. Turn on the power switch. Caution: the probe will get hot. Do not touch
the metal shaft or tip. The amber light will remain constant for about one
minute. The side holster is helpful for safely securing the thermal probe
when not in use. Keep tip away from kit foam or other damageable
materials.
5. Wait about five (5) minutes for the Hot Probe temperature to stabilize
fully. At this time, the amber light will blink regularly, signaling the probe is
at the correct operating temperature. The display LCD should read 0000 +/-
2.
6. Operation Check: Place the provided Daily Qualification Standard (DQS)
into the jaw of the alligator clip. The standard is on a ball-chain attached to
the instrument handle. Fig. B.
7. Contact the Hot Probe tip to the test metal for only two seconds. Apply
just a little more pressure than when using a ballpoint pen, around (70 psi).
The display should read 60 +/- 10. This re-standardization step shall be
performed at the start and finish of each run and at least once during every
hour of continuous operation. This concludes the Operation Check.
8. Next, prepare your actual test metal. Test metal and probe tips must be
clean and free of scale. Wipe metal surface with a cloth or abrade with an
abrasive.
9. Select best Cold Circuit lead for your application (page 8 for details)
Either:
A) Alligator Clip
B) The Wand
C) The Heavy Block
10. Contact the Hot Probe tip against the test metal for one second and read the displayed numeral. It might be
necessary to press down on the sample one or two times for a precise reading. It is important not to keep the
probe in contact with the metal for more than two seconds. After two seconds, the readings become erroneous
because the values can drift due to heat dissipation. Wait two seconds between tests to allow the probe
temperature to stabilize.
11. Compare the displayed TE numeric readings to acceptable metal standards, or the supplied chart. The chart
provided is suggested values and is useful as a guide. The TE-3000 is a capable instrument as long as the
variations of one metal have a 10 point ‘buffer’ from the fluctuations of a second metal. It is also possible that
different alloys give the same TE reading. Some materials might provide slight variations in TE readings due to
heat treatment during alloy formation. Ambient conditions can change, influencing test results.
12. When the instrument is not in use, turn off the power.The Hot Probe takes a few minutes to cool down.

DQS if Alligator Clip over-hangs the
workbench.

UNKNOWN ALLOY IDENTIFICATION
The Prospector is best to be used as a sorter,not as an identifier or an analyzer. Measure the
unknown alloy in several places on the surface to get a range of numbers. Then compare this
reading with the table of Alloy TE Readings. If a match is found, it does not prove that the alloy
is the one in the table, it only suggests it may be. More must be known about the possibilities,
based on, for example, the alloys in use at your plant. Confirmation of the alloy type can often
be made with Koslow chemical spot tests. An alloy reading between 3 and 14 is probably a
300 series stainless steel and a confirming color spot test for molybdenum would indicate the
alloy is SS316.
Similarly, a reading of –110 could be a chrome-moly steel or CP titanium. A chemical color
spot test for iron would confirm the chrome-moly steel because there is very little if any, iron in
titanium. If the alloy is not found in the table, a chemical lab analysis must be performed. A
sample of the alloy should be kept handy, and its TE number recorded.
The TE number has been compared to hardness. Just as it is possible for two different alloys
to have the same hardness, two samples of the same alloy can have different hardness
resulting from different heat treatment. Both the TE number and the hardness are affected by
the crystal structure of the alloy.
SAFETY
•Do not touch any metal parts of the probe while in operation.
•Do not use the TEAS for any application other than its intended use.
•Let the hot probe cool to room temperature before changing tips.
•Let the probe cool to room temperature before storage.
•Never attempt to perform repairs, diagnostics, or maintenance while the unit is plugged
in.
•Mishandling or leaving TEAS unattended can result in a burn or fire.
•Do not modify the hot probe or use it with damaged parts.
•The tip temperature of your hot probe can reach more than 120°C.
•Repairs should only be performed by a factory-qualified technician.
IMPORTANT CONSIDERATIONS
It is crucial for the user to consider the possible adverse effects of using TEAS on live power,
components, or sensors. This is especially important where economic property loss or human
life is involved. It is vital that the user employs a satisfactory system design of automated
equipment. It is agreed between the Buyer and Koslow that safe system design is the buyer’s
responsibility. Do not use in a wet environment.
SELECTING A WORK LOCATION
•The workspace must have access to a properly grounded outlet whose output voltage
matches that of your plug. If using the TEAS outside the USA, power transformers may
be needed. Cord adapters may be necessary for plug configuration.
•Don’t modify the factory supplied cord.
•Workspace is preferably on an inside wall, or at least away from windows.
•The workspace should not be in the direct path of airflow from AC or furnace vent.

5
HELPFUL HINTS
•Do not operate TEAS close to a fan or point of high air motion. Wind will dissipate the
heat from the test area, causing poor readings.
•Hold the Hot Probe in contact with the test metal for only about 2 seconds & read the
display. Lift probe off test metal for two seconds allowing probe temperature to stabilize.
Repeat this cycle. Rushed testing without pauses may result in reading drift.
•Be sure the test metal and hot tip of the probe remains clean.
•If tip becomes marred or misshaped, unscrew and replace.
•Confirm that the tip is completely screwed tightly into the probe shaft. Loose tips could
give weak readings. Use of a hand-held crimping tool (Part No. TE-3000 F) is
recommended for proper torque without scratching tip.
•
PREVENTATIVE MAINTENANCE & CALIBRATION
•The Thermoelectric Alloy Sorter Model TE-3000-HD is supplied with an Initial Certificate of
Calibration. Koslow Scientific Co. recommends yearly calibration services known as a
“field” Certificate of Calibration (Service No. TE-3000-C). This certificate contains before
and after calibration data and the expected manufactures criteria. Aspects of the document
are N. I. S. T. traceable.
•Maintain kit by storing in a cool, dark place.
•Annual calibration cycles can be logged on the last page of this instruction manual.
Maintenance items are the responsibility of the customer/user. Failure to observe these
recommendations may adversely affect the operation of the equipment.
SIGNAL JACKS
The TE-3000-HD is supplied with one black and one red female banana jack on the top of the
instrument. These terminals can be used to interface with automation equipment, PLC’s
(Programmable Logic Controls) and data logging equipment. The output signal is an analog DC
millivolt signal.
DAILY QUALIFICATION STANDARD
The kit includes a Daily Qualification Standard, (DQS) a
1-inch square plate of a nickel alloy. The DQS is
attached to the side of the machine with a small chain.
The DQS is principally used to confirm repeatability. It
acts as a calibration registration point for all the other
readings.

6
COLD CONTACTS
The TE-3000-HD contains three choices for the “cold contact” part of the circuit. One cold
circuit must be connected with the BNC connector to the Alloy Sorter before taking a test. Be
sure the cold circuit makes solid contact with test metal first, then make contact with a hot
probe.
•The Alligator Clip: Hands-free contact with the metal surface of small and large parts.
Clipping it on ensures good electrical connection.
•The Heavy Copper Block: Choice for non-clamp or delicate plated surfaces. It can also
hold cylindrical bearings, spherical bearings, and small parts. The heavyweight of the
block also allows it sit securely on a workbench. Use the 6 foot male to male BNC to
connect the TEAS.
•The Wand: Requires two hands. Is very fast to use. Leave test metal in place and move
Wand and Hot Probe to part. Wand contacts metal first then thermal probe.

HOT PROBE TIPS
A variety of tip configurations are available. The TEAS is
furnished with a Blunt shaped tip. Other available
shapes are Conical (included), Spherical and Dolphin
Nose. Different shapes aid in repeatable metal contact at
a perpendicular or tangent angles. Custom shaped tips
can be fabricated to your specifications. Give us a call to
learn more.
Replace probe tips when the tip is marred, misshaped, or
no longer providing stable readings. Confirm that the tip
is completely screwed tightly into the probe shaft. Loose
tips could give poor readings. Use of a handheld crimping tool is recommended for proper
torque without scratching tip. Do not tamper with machine screws on the probe shaft. Remove
Alloy Sorter from power when changing tips.
Tip Removal
1. Remove power from the TE-3000 by unplugging.
2. Allow equipment to cool.
3. Hold pliers (Koslow Part No. TE-3000-F) in a horizontal
position.
4. Insert the old probe’s tip into the jaw of the pliers.
5. Twist probe handle counter-clockwise until the tip can
fall out.
6. Discard old tip. See the demo video on YouTube.
New Tip Insertion
1. Insert a new tip by hand. Twist clockwise. Be careful not to damage the threads. The new tip
should be inserted about halfway by hand. A very small drop of dielectric silicone can be used
to lubricate the screw threads.
2. Hold pliers in a horizontal position. (Koslow Part No. TE-3000-F)
3. Hold TE probe (in other hand) vertically, with the tip up and the cord down.
4. Align the tip into the jaw of the pliers. Gently squeeze the probe tip. Do not crush the probe tip.
5. Rotate the handle part of the probe only. Do not rotate the pliers. The pliers should remain
perpendicular to the probe.
6. The tip should be installed firmly. Small scratches on the tip will not inhibit performance.

*ALLOY SEPARATIONS CHART
* TE Readings for reference only. Subject to customer’s independent evaluation and testing for
suitability. The TE readings in the above chart are reflective of actual results of metal samples, but may
not necessarily reflect results observed in the field. The readings included in this chart are intended to
be used as a reference to aid the instrument user in determining the efficacy of the Thermo-Electric
Method.
LIMITATIONS
Thermoelectric response is inherently a comparison method of identification because individual
elements cannot be quantitatively determined. Some alloys differ only slightly in one or two
elements and the change in voltage on the tester is too slight to produce a different reading.
Some alloys have elements in them which may offset one another to produce nearly identical
readings overall. Alloys of identical chemical makeup but with different physical hardness
structure usually have different readings.
Additionally, the thermoelectric response procedure cannot differentiate between Stainless
Steel 316 and 304. The Spotter 316 can do the job. For more information, check out
https://www.koslow.com/select_metal_test_kit.

ALLOY SEPARATIONS CHART
* TE Readings for reference only. Subject to customer’s independent evaluation and testing for
suitability. The TE readings in the above chart are reflective of actual results of metal samples,
but may not necessarily reflect results observed in the field. The readings included in this chart
are intended to be used as a reference to aid the instrument user in determining the efficacy of
the Thermo-Electric Method.
LIMITATIONS
Thermoelectric response is inherently a comparison method of identification because individual
elements cannot be quantitatively determined. Some alloys differ only slightly in one or two
elements and the change in voltage on the tester is too slight to produce a different reading.
Some alloys have elements in them which may offset one another to produce nearly identical
readings overall. Alloys of identical chemical makeup but with different physical hardness
structure usually have different readings.
Additionally, the thermoelectric response procedure cannot differentiate between Stainless
Steel 316 and 304. The Spotter 316 can do the job. For more information, check out

TROUBLESHOOTING
Symptom
Cause
Remedy
Difficult to reassemble unscrewed
and opened probe.
Only to be serviced by
Koslow service technicians. Do not open the probe screws.
Display reads 0000 even when
making contact with test metal. Open circuit or no reading.
Test metal should be free of paint,
grease and other non-conductive
coatings. Check Cold Contacts.
Testing the same area multiple
times, and the reading changed
from passive to non-passive.
Do not perform multiple
tests in the exact same test
spot.
Allow to cool to ambient temp before
testing a second time.
The Tip appears discolored. The hot tip may change
from a normal copper color
to others from temp
changes.
Wipe the tip with gentle abrasive.
The number 1 is on the display and
does not change.
Damage to internal
components.
Contact Koslow for calibration and
repair.
Very small parts and wire are
difficult to test.
It is necessary to contact
wire at two points.
Place small parts such as small
fasteners or wire on a clean
conductive block for testing.
Cannot test all areas of a tank.
It can be difficult to reach
high or deep into
equipment.
Accessory available. The extension
handle is up to 4 feet long. (Part No.
TE -KFG)
Cannot get a 60 (±5) with the
standard Alloy C-276.
The TEAS readings are too
high or too low.
•Is the tip of the probe tightly
installed? Use the pliers to
make sure the hot probe tip
is tight.
•Are metal tips and parts
clean?
•Are you working close to a
fan, vent, or air movement?
•Are you working close to a
large machine that can be
causing electromagnetic
interference?
Readings are climbing or falling over
time.
The Hot Probe is to only
make contact with the test
metal for one or two
seconds.
•Press the hot tip to the metal
with light downward pressure
(about 70 psi).
•Wait for 5 seconds interval
between tests.

Instructions for Returning a Koslow Instrument for Factory Calibration
We appreciate your confidence in Koslow test kits. We recommend an annual factory calibration.
You provide:
1. Pack your kit, with all its parts, in a well-cushioned and corrugated carton.
2. Include the Daily Qualification Standard (one inch square metal sheet).
3. Include your contact information with the shipment: Name, Phone and Email.
4. Include a note with comments to our technicians. We appreciate any technical observations that
may help our technicians service your equipment.
5. Don’t send a payment or purchase order yet! Call for the base price for calibration. A service
technician will need to first review the instrument’s condition before a final price can be
established. Return shipping methods must also be estimated and added.
6. Our expectation is to service equipment that is reasonably used. For the safety of our
personnel, please clean unsanitary equipment prior to submission. If objectionable surface
materials are found, the kit may be removed from our labs and shipped back to owner without
work performed.
7. Ship your kit complete to the address below. Include Return Authorization Number for the
outside of the shipping carton: RMA 1113-68.
Koslow Scientific Company
Attn: Calibration Dept. RMA 1113-68
172 Walkers Lane
Englewood, NJ 07631
We will provide the following:
1. A factory Certificate of Calibration. This includes: electronics verification traceable to N.I.S.T.
standards, “As Found” before data and “As Left” after data.
2. A maintenance checklist to keep the consumables fresh for another whole year, with the
suggested option to remedy missing or damaged parts.
3. In the course of calibration, if a repair is necessary for the completion of the calibration, we will
add cost to the formal quotation.
4. You will be notified by email with a formal quotation within three business days.
5. Equipment abandoned at our location for longer than 60 days will be disposed of.
6. We thank you for the opportunity to serve you.
