The Therma 22 Plus incorporates an easy to use waterproof Lumberg screw-locking type connector, allowing a wide range of interchangeable Type T Thermocouple and Thermistor probes to be used.

The Therma 22 Plus waterproof thermometer offers IP66/67 protection and is housed in a robust waterproof white ABS case. The thermometer utilises state of the art electronic circuitry, designed for reliability and ease of use and can be submerged or washed under a running tap - ideal for food processing applications where cleaning is paramount.

The Therma 22 Plus measures temperature over the range of -199.9 to 400 °C with a 0.1 °C resolution, auto-ranging to 1 °C resolution over the range of 300 to 400 °C.

The Therma 22 Plus features a large easy to read, LCD display with max/min, °C/°F, hold, open circuit, low battery indication and an optional backlight. The unit also incorporates an auto-power off facility that automatically turns the instrument off after ten minutes, maximising battery life.

The instrument is housed in an ergonomic, ABS case that includes 'Biomaster' additive which reduces bacterial growth. Each unit has an integrated rubber seal to ensure complete water resistance and helps to reduce the possibility of damage in harsh environments.
