Part Number 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
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 unit.
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. Click here to view suitable probes, or click the accessories tab. The Therma 22 is priced exclusive of probe.
optional accessories
The protective boot helps to protect the instrument against accidental damage. 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
what is Biomaster?
Biomaster additives are powerful broad-spectrum inorganic, silver-based biocides for use in plastics, helping to reduce hygiene risks. The concentration of silver, in the patented anti-microbial active agent in Biomaster, provides a release of silver ions on demand, which in turn safely inhibits microbial growth.
