Therma 22 thermocouple and thermistor thermometer
The Therma 22 hand-held thermistor and thermocouple thermometer is ideal for those who require the versatility of both thermocouple and thermistor probes in a single compact thermometer. The thermistor sensor provides greater accuracy in food processing, whereas the type T thermocouple sensor extends the measurement range and provides faster response when needed. Simply insert your preferred probe into the Therma 22, and the thermometer will take quick, accurate measurements. Therma 22 has an easy-to-read LCD display with open circuit and low battery warnings. The instrument displays temperature ranging from -39.9 to 149.9 °C (thermistor) or -199.9 to 400 °C (thermocouple) (type T thermocouple).
