This curve gives the value that is necessary to add to the reading, in order
to take variations due to non-linearity into account.

4. OPERATION
• Select the range required: up to +200°F or +2000°F for Model K2000F
or select mV input for Model ST2-2000.
• Make sure that the sensor connected is suitable for the measurement
about to be taken.
• Position the sensor at the point of measurement.
• Wait a few seconds for the sensor to stabilize (refer to sensor response
time in Section 6).
• Check the reading when the indication settles.
The body of the thermometer must be kept within the temperature
range 32°F to 122°F (0°C to +50°C).
5. BATTERY REPLACEMENT
• The 9V battery is accessible through the back of the instrument.
• Unscrew and remove the rear half of the case.
• Replace the battery and put the case back together.
Always disconnect the sensor from the thermometer before open-
ing the case.

6. SENSORS AND PROBE EXTENSIONS
General Notes
ISOLATION
The thermocouple is incorporated into the extreme tip of each of the sen-
sors described in this booklet. The thermocouple is solid with the body of
the sensor.
SENSOR RESPONSE TIME
The response time of a thermocouple is the time taken for it to settle to a
new value after the introduction of a temperature step. For a thermocouple
plugged into a medium having a high caloric value, good thermal conduc-
tivity and good thermal contact, the response time should be extremely
short (intrinsic response time). If the thermal medium is unfavorable (e.g.
calm air) the actual response time could attain 100 times or more of the
thermocouple itself. Values for the K2000F and ST2-2000 sensors have
been established under the following conditions:
• For supple and auto-grip surface sensors in contact with a polished
stainless steel plate coated with silicon grease.
• For the air sensor, in agitated air (1 m/s).
• For the other sensors, by immersion in agitated water at 194°F (90°C)
(agitation speed: 0.3 to 0.5 m/s).
TEMPERATURE RANGE
The temperature range for each sensor is given for use in chemically neu-
tral environments. The introduction of a sensor into a corrosive medium
could shorten its life or limit recommended working range.
SENSOR CLASSIFICATIONS
K type thermocouple sensors are either Class I or II (according to stan-
dard NF C 43-322). Class I is denominated reduced tolerance and Class
II standard tolerance.
CLASS I ± 3°F (1.5°C) ± 0.4% reading
CLASS II ± 5°F (2.5°C) ± 0.75% reading
-40°F 32°F 626°F 707°F 1652°F

Digital Thermometer Model K2000F and Temperature Probe Model ST2-2000 9
Sensors
Needle Sensor SK1
Working Range: -58°F to 1472°F (-50°C to 800°C)
Time Constant: 1 second
Length: 5.9”
Class: II (NF C 42-322 standard)
Bevelled tip needle sensor for insertion into pastes, fats, liquids etc. The tip
of the sensor must be inserted at least .79” (20mm).
Formable Sensor SK2
Working Range: -58°F to 1832°F (-50°C to 1000°C)
Time Constant: 2 seconds
Length: 39”
Class: II (NF C 42-322 standard)
This sensor can be formed to suit most needs. Curvature must never be
less than twice the diameter of the sensor shank. This sensor comprises
a stainless steel sheathed thermocouple, it can resist corrosion in a great
number of hot liquids and gases.
Semi-Rigid Sensor SK3
Working Range: -58°F to 1832°F (-50°C to 1000°C)
Time Constant: 6 seconds
Length: 19.6”
Class: II (NF C 42-322 standard)
This sensor comprises a sheathed thermocouple (same as SK2), but it
does not bend as easily. Though, it does allow enough exibility to reach
some of the more awkwardly placed measuring points.
Surface Sensor SK4
Working Range: -32°F to 482°F (-0°C to 250°C)
Time Constant: 1 second
Length: 5.9”
Class: II (NF C 42-322 standard)
The tip is particularly well adapted to point measurement on small sur-
faces: electronic components, radiators, solar panels, heat exchangers,
etc. Hold the probe perpendicular to the surface to ensure good contact.
The surface should be at. Change the position of the probe slightly if
necessary to obtain the highest reading. The use of silicon grease can
improve the contact quality.
