Therma 1T Thermometer - High Accuracy Thermometer

The Therma 1T High Accuracy Thermometer from ETI is designed for professionals who require rugged precision across diverse industrial, laboratory, HVAC, and food safety applications. Built in the UK, this advanced digital thermometer accommodates interchangeable Type T thermocouple probes (sold separately), offering maximum flexibility and ultra-responsive measurements.

With a temperature range from −100 °C to +400 °C and a resolution of 0.1 °C (up to 300 °C; 1 °C thereafter), the Therma 1T delivers exceptional accuracy of ±0.2 °C ± 0.1 % of the reading. Housing its electronics in a robust ABS case infused with Biomaster antimicrobial protection, the unit is thoughtfully designed for hygienic and long-term use.

A clear 12 mm LCD display shows readings alongside open-circuit error and low battery alerts. Powered by 3 × AAA batteries, the device offers a minimum of 10,000 operating hours (~5 years) and features an automatic 10-minute shut-off (which can be disabled) to conserve power.

Each unit is supplied with a free traceable calibration certificate and comes with a two-year manufacturer’s guarantee, ensuring its readiness for HACCP, ISO, and laboratory compliance needs.
