Unit 1 - 6115 4 St SE
Calgary AB  T2H 2H9

TPK-03 Immersion Probe K-type Thermocouple (-50 to +700°C)

ID: 3108_2

This K-Type thermocouple measures temperatures from -50°C to 700°C and connects to a Phidgets thermocouple board.


Replaced by the TMP4106 - K-Type Probe Thermocouple 11cm

The 3108 - K-Type thermocouple can take continuous temperature readings between -50°C to +700°C with a ±0.75°C accuracy. The 3108 can also take a instant, single temperature reading between -100°C to +900°C.

It is typically used to take the temperature of liquids and gels.

Thermocouple Interfaces

This K-type thermocouple can be read by connecting it to any of the thermocouple interfaces in the list below.

Note: On the 1051 or TMP1100, connect the white thermocouple wire to the (-) terminal block and the red wire to the (+) terminal block.
On the 1048 or TMP1101, connect the white wire to G and the red wire to input terminal block (numbered 0 to 3).

Function 3108

- White - / G

Thermocouple Accessories

Thermocouples cannot easily be soldered, since adding an additional metal junction will throw off the readings. The following products will help connect or extend thermocouple wires.
