The Therma Differential digital thermometer is an excellent HVAC tool, allowing users to simultaneously utilise two type K thermocouple probes. The display can be toggled to showcase either probe T1 or T2 temperature, or the temperature difference between probes T1 and T2 (T1-T2). This flexibility is advantageous for measuring scenarios such as the temperature drop across radiators or the temperature rise or fall of two items.
With a temperature measurement range of -99.9 to 299.9 °C and a 0.1 °C resolution, or 300 to 1372 °C with a 1 °C resolution, the thermometer features a custom LCD display indicating °C, T1, T2, diff, hold, open circuit, low battery indication, and an optional backlight. The unit includes an auto-power-off feature that automatically turns off the instrument after approximately ten minutes, extending battery life.
Each thermometer is encased in a robust ABS case with an integrated rubber seal, ensuring complete water tightness and reducing the risk of damage in challenging environments.
