Therma 22 thermocouple thermometer

Product code: 227-022

Therma 22 thermistor / thermocouple thermometer. Excluding probe.


  • Range -199.9 to 399.9 °C
  • Fast response with high accuracy
  • Wide range of interchangeable probes
  • Auto power facility
  • Case includes Biomaster anti-bacterial additive


The Therma 22 hand held thermistor and thermocouple thermometer has been specifically designed for those who need the versatility of both the thermocouple and thermistor probes in one compact thermometer.

The thermistor sensor gives greater accuracy for food processing, whilst the type T thermocouple sensor extends the measurement range and provides faster response, if required.
Simply plug the probe of your choice into the Therma 22 and the thermometer will take fast, accurate measurements.

The Therma 22 features an easy to read, LCD display with open circuit and low battery indication.
The instrument displays temperature over the range of -39.9 to 149.9 °C (thermistor) or over the range of -199.9 to 399.9 °C (type T thermocouple).

The unit is housed in a robust ABS case that includes ‘Biomaster’ additive which reduces bacterial growth.
The auto-power off facility maximises battery life, turning the instrument off automatically after ten minutes.

The Therma 22 thermometer incorporates a Lumberg screw-locking type connector, allowing a wide range of interchangeable probes to be used.
ETI offers an extensive range of interchangeable type T thermocouple probes.
