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 Therma 22 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.

What is Biomaster?

Biomaster additives are 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.

To fulfill your order as quickly and efficiently as possible, we sometimes will split your order into a number of different packages so that we could take advantage of the items in stock at different warehouses.  Items you order from Complete Safety Supplies may sometimes be sent in more than one delivery. For example, you may receive multiple deliveries if your order contains an oversized item that needs to be dispatched separately. Regardless of the number of deliveries you receive, you'll only be charged the amount that was originally quoted to you at the time you placed your order. Orders will only receive one delivery charge.
