Therma 22 Plus Thermometer

The Therma 22 Plus is a robust and waterproof digital thermometer specially designed for professional food processing, HACCP controls, and industrial applications where reliability and hygiene are essential. Thanks to its IP66/67 certification, this measuring instrument can be rinsed or even immersed underwater, simplifying cleaning in demanding environments.

This thermometer accepts both thermistor and Type T thermocouple probes, offering flexibility in sensor choice for various measurement tasks. The easy-to-read LCD display shows current temperature values, with additional functions such as max/min values, hold mode, open circuit indication, low battery indication, and optional backlighting for better visibility.

The Therma 22 Plus measures temperatures across an extremely wide range—from deep-frozen products to high process temperatures—and comes standard with a free traceable calibration certificate compliant with the European standard EN 13485, ensuring accurate results.

Please note: this thermometer is sold without a probe; choose the appropriate thermistor or thermocouple probe separately for your application.
