    ETI Therma Differential Thermometer

    The ETI Therma Differential Thermometer is an ideal HVAC thermometer as it allows the user to use two type K thermocouple probes simultaneously. The display can be switched to show probe T1 or T2 temperature or the difference between probes T1 and T2 (T1-T2). This allows, for example, the temperature drop across radiators or the temperature rise or fall of two items to be measured.

    The Therma Differential measures temperature over the range of -99.9 to 299.9 °C with a 0.1 °C resolution or 300 to 1372 °C with a 1 °C resolution. The thermometer features a custom, LCD display with °C, T1, T2, diff, hold, open circuit, low battery indication and an optional backlight. The unit incorporates an auto-power off facility that automatically turns the instrument off after approximately ten minutes, maximising battery life.

    Each thermometer is housed in a durable, ABS case that has an integrated rubber seal to ensure complete water tightness and help reduce the possibility of damage in harsh environments.



    • Dual-input thermometer – measure temperature from two points simultaneously
    • Works with a wide variety of interchangeable type K temperature probes (sold separately)
    • Ideal for HVAC work – measure the temperature drop across radiators or the temperature rise and fall of other objects
    • Measure from each channel individually (T1 or T2) or measure the difference (T1-T2)
    • Temperature measurements from -99.9 to 299.9°C with resolution of 0.1°C and 300 to 1372°C with resolution of 1°C
    • Data hold function temporarily stores current values shown on the screen
    • MAX/MIN mode calculates the maximum and minimum temperatures taken over a period of time
    • Automatic power off helps to save battery life
