Therma 22 Plus Thermometer

The Therma 22 Plus is a rugged, waterproof digital thermometer specifically designed for professional food processing, HACCP inspections, and industrial applications where reliability and hygiene are essential. Thanks to its IP66/67 certification, this measuring device can be rinsed under water or even submerged, making cleaning easier in demanding environments.

This thermometer is compatible with both thermistor and Type T thermocouple probes, giving you flexibility in choosing the right sensor for various measurement tasks. The easy-to-read LCD display shows current temperature readings, along with additional features such as max/min values, hold mode, open-circuit detection, low-battery indicator, 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 in accordance with the European standard EN 13485, ensuring accurate results.

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