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 400 °C (type T thermocouple).

Housed in a robust ABS case that includes Biomaster product protection which reduces bacterial growth. The auto-power-off facility maximises battery life, turning the instrument off automatically after ten minutes. 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. The Therma 22 is priced exclusive of probe. To add recommended probes and other accessories select your choices from the 'Add Accessories' dropdowns, then click 'Buy Now! button.

Optional accessories
The protective boot helps to protect the instrument against accidental damage and when used makes the instrument splashproof to IP64. The stainless steel wall-mounted thermometer holder stores the instrument safely when not in use (screws not supplied). Thermistor test caps, suitable for testing the accuracy of the Therma 22, are also available.
