    With this set for the sectors of heating engineering, sanitation, refrigeration and air conditioning technology, you will be ready to begin work straight away. With its two connectable probes, the 2-channel testo 922 temperature measuring instrument measures temperatures in parallel and can determine the differential temperature in a matter of seconds. Once the measurement is complete, you can safely store your equipment in the handy bag supplied.

    HVAC/R set including testo 922 temperature measuring instrument – key benefits

    The testo 922 temperature measuring instrument is ideal for measuring differential temperature in the sanitary and HVAC/R sector:
    • Two temperature probes TC type K can be connected to the measuring instrument (two surface temperature probes with Velcro are already included in the set)
    • Connection of another optional temperature probe possible via radio transmission
    • Display of temperature values and differential temperature
    • Hold button to retain the readings
    • Continuous display of min. and max. values
    • Illuminated display
    The temperature probe with Velcro enables you to measure the surface temperature of pipes, e.g. heating pipes:
    • The temperature probe with Velcro is ideal for pipes with pipe diameters of up to 120 mm. The thermocouple sensor for measuring temperature is attached to a 20 mm wide, 395 mm long strip
    • The Velcro fastener on this strip allows the temperature probe to be attached quickly and easily
    • The temperature probe features a 1.5 m cable
    • Measuring range -50 °C to +120 °C, accuracy ± 1.5 °C
    • Response time t99 90 sec - for optimum heat transfer between surface probe and measurement object, we recommend using our optional silicone thermal conductive paste
    Handy bag for temperature measuring instrument and probes:
    • Flat case design with zip fastener and rounded, solid edges
    • For safely storing measuring instrument and probes
    • The bag is easy to open, the measuring equipment is easy to take out, practical for everyday use

    • testo 922 temperature measuring instrument including batteries and calibration protocol
    • Two temperature probes with Velcro for surface measurements on pipes (item no. 0628 0020)
    • Handy bag
