Introduction
Thank you for selecting The Alloy Scout (Part No. 1545) Stainless Steel Identification Kit. This rapid
spot test kit precisely determines the presence of three common elements alloyed in stainless steels:
chromium, nickel, and molybdenum. It is especially effective at sorting between non-stainless, SS 304,
and SS 316. If the formulated test paper turns a prescribed color, the results are positive for the
corresponding element. No other element will interfere or produce the prescribed color reaction. Spot
tests are easier, faster, and cheaper than chemical analysis in sorting stainless steel scrap or inspecting
upcoming and outgoing stock.https://youtu.be/d-C7DDK7SJI
Use this kit with the utmost confidence. It is an ASTM approved method. The Scout is the first bottle-
free chemical spot test kit. Koslow’s patented Dry-Spot Technology utilizes age-old and acceptable
chemical methods but eliminates the need for bottles of solutions. Instead, cartridges dispense very
small controlled quantities of color reacting reagents.
ASTM 1476-95 is the standard guide for metals identification, grade verification, and sorting.
The Scout kit includes a small metal standard of stainless steel 316 to be used as a testing reference.
Working side by side with a known sample will show what a positive result looks like before attempting
tests on lesser-known materials. It also assures the user that the equipment and procedures are
working as they should.
The Alloy Scout (Part No. 1545) is designed to be used by inspectors, stainless steel fabricators,
process and quality control engineers, and other finishing technicians are working in applications where
verifying the grade of stainless steel is critical. With colorful results, non-technical personnel can easily
inspect parts as part of a routine quality control program. This kit can be used on many types of metal
surfaces: large tanks, pipes, welded areas, wire, and even small parts (1 sq. cm.).
Read this manual before operating your kit. This manual functions in two ways, firstly as a step by step
guide to help the user operate the instrument and secondly as a handy reference guide. This instruction
manual is written to cover as many anticipated questions as possible concerning the Alloy Scout. If
there are any doubts about the use of this tester, do not hesitate to contact a Koslow Technical Support
Representative at 011 (201) 541-9100. We want you to be happy and satisfied with your results.

Selecting a Work Location
Perform work on a chemically resistant surface. Use a workspace with access to a properly ventilated
airflow. Work in sufficient lighting to view color test results. Pink-tinged fluorescent lighting can give
poor color visibility; whereas daylight provides excellent visibility to color perception. This kit is for
industrial and commercial use only. Keep away from children.
Initial Test Preparation

Quick Instructions
1. Review safety information and initial test preparation. The probe should
be loaded with the Dab Cartridge and battery pack. Pull to remove the tip
cap.
2. Place a single, Test Strip onto metal surface.
3. Align the Cartridge tip over the center of the paper and gently push the
probe. The Cartridge tip retracts into the probe. This can be achieved in
one smooth motion.
4. The LED indicates that the necessary electrical contact has been made.
Notice that the outside ring of the tube makes contact with metal surface.
Reposition your placement if the blue light does not go on.
5. Hold the blue light on for about 1 second. Complete the electro-spot
process by lifting the probe up, off the paper.
6. Turn the paper over. Any amount of prescribed color indicates a
positive test.Wait about a half a minute for the color to fully develop. After
a few minutes, the color may slowly fade away.
7. Conclude test by comparing results to a known standard. Return the
protective tip cap to the cartridge tip. Press cap into cartridge tip till it
snaps shut.

The Electro-Spot Model 6 Probe
The Probe
The Electro-Spot Model 6 Probe (Part No.1544P) is both a DC power supply and an electrochemical
dispensing method. The internal cartridge contains a dilute acidic solution, which is very slowly
dispensed through the porous tip. Longer testing time may be needed depending on the life of the
batteries and the moisture levels of the cartridge. Maintain the bottom ring by keeping clean with a
gentle abrasive. When performing a test, the tip and the ring do not need to be perfectly aligned with
paper — current flows between the tip & the test strip, and also between the ring & test metal.

The Current Indicator LED
When the probe is correctly brought in contact with the test metal through the test paper, the blue LED
signals the beginning of the Koslow Electro-Spot Process. This process extracts a small amount of the
test metal’s elements onto the test paper. The LED indicates that current is flowing from the battery to
the test metal surface. Most importantly, it is the starting cue for the countdown. The operator only
needs to count to five. After the time has elapsed, merely lift the probe off the test paper, ending the
Electro-Spot Process. Next, watch for the color reaction on the test paper.
Note: It is common for the LED to blink if metal-to-metal contact is briefly lost. Resume or estimate the
total accumulated time. Slight lapses of contact are not a problem. Generally holding the probe straight
up and down is best but sometimes a slight angle as illustrated below may increase metal to metal
conductivity.
Sometimes, better electrical contact can be obtained by bringing the probe down on a slight angle.
Test Strips
Test Strips are specially formulated rectangular paper strips that change color with specific element
contact. The test requires two points of contact: at the ring of the Barrel and the Cartridge tip. Papers
are disposable.
Note: the Cartridge Tip can be damaged or contaminated if it is in direct contact with metals. Be sure
the test paper is between the probe tip and test metal. It is normal if the Tip appears white to pale
yellow. The paper seperation protects the sensitive tip from contamination. The color spot may develop
on any part of the Strip. Contact (any part) of the strip with the tip.
8
The Dab Cartridge
The Dab Cartridge contains a unique electro-chemical dispensing system. When used correctly, a
very small volume (0.0001 mL) of a proprietary solution releases onto the test paper. Because of the
low volume of solution dispensed, one cartridge can be used for as many as 500 tests. When in
contact with the Test Strip, it should make a moist circle about 5 mm. in 1 second of use. If it cannot
make a 5 mm spot in 1 second, replace the Cartridge. Test results are rarely identical over the entire
metal surface. These color determinations have been empirically determined in the labs of K.S.C.
Do not disassemble the sealed Cartridge. The contents may be corrosive. The Cartridge
cannot be refilled or serviced in the field. It is disposable, and replacements are available
from K.S.C.
The Qualification Standard Metal
First, perform a test on the provided calibration standard. Part Number 1542S. This sample
has been provided as a reference. The test standard is a square piece of stainless steel (SS-316)
metal plate (25mmx25mmx2mm). Testing it will reveal a pink spot. Keep this standard with the kit. If
kept clean, the standard can be a reliable comparison material indefinitely.

Testing Small Parts
Testing small parts is comfortable with the Alloy Scout. If a test metal part is smaller than 0.5 inches,
place the part on an electrically conductive sheet such as aluminum foil. Contact Koslow for a little
part testing diagram.

Battery Recharging and Installation
The Alloy Scout operates on 10.8 volts. The batteries supplied are rated at 3.6 volts each. Load three
batteries into the battery spacer adapter. The battery pack is designed for high-speed and easy
loading into the Scout 316. It is essential to install the cells and the adapter correctly. Observe the
polarity! The arrow on the black adapter points (up) in the direction of the screw cap. On the pack,
you will notice that the two negative signs go down toward the direction of the cartridge. The battery
pack gets loaded into the Tube with the arrow pointing up (toward the spring cap).
Note: Observe the adapter polarity! When reloading the adapter pack with fresh batteries, the flat end
on the battery gets pushed into the spring. Each cell should be inserted into the pack sleeve with the
flat side into the spring. Only replace batteries with 3 of the same type of battery. Never mix battery
types.
The battery can be replaced by unscrewing the cap and removing the pack. Inside the pack; the
internal battery is rechargeable lithium (Li) ion battery and is suitable for years of use. The battery can
be easily charged by utilizing a Li-ion charger (available from Koslow, sold separately). Each battery
has an internal short circuit and an overcurrent protection circuit. The power pack does not supply
power to the unit if the batteries are not correctly inserted. If the batteries are not to be used for a long
period, unload from tube and adapter and store batteries in the carry case foam. Fully charged
batteries are close to 4.1 volts each.
Use special care in the charging of batteries; there is a risk of fire. Follow the charger manufacturer’s
instructions for safety. Before battery disposal, tape or insulate the ends of the battery to prevent
short-circuiting, even when they are expired.
Maintenance and Storage
•Always keep the tip cover on the Cartridge when not in use. The Cartridge Tip is made of a
porous plastic material. Keep the tip clean of grease or debris. If the Tip gets dirty, wipe with a
drop of water and a paper towel.
•Always keep unused Test Strips in the case.
•To clean the exterior of equipment, use only a damp cloth. Do not submerge.
•Metal contact points may be gently rubbed with plastic abrasive. Also, a silicone dielectric paste
can be used on the internal contacts on the cartridge and the battery adapters.
•Keep all the kit parts in the carry case and store in a cool, dark environment.
Koslow Scientific Company cannot accept any responsibility for damage or malfunction to the tester
