Testo 922 is a temperature measuring instrument which is especially suited to applications in the HVAC field. The measuring instrument records the temperature values of two connected thermocouple probes, and shows these simultaneously together with the differential temperature in the display.
Temperature measurements; measurements with up to three temperature sensors; direct display of temperature differences: the Testo 922 digital temperature meter is ideal for professional use in the fields of heating, plumbing and air conditioning.
With the TopSafe, and the probe plugged in, the measuring instrument has protection class IP65.
Flow and return temperature measurement on heating systems
To ensure the heating system is set correctly and efficiently, the flow and return temperatures must be measured. If it is not set correctly, either the requisite heat will not be provided or too much energy will be injected into an overly high flow temperature, i.e. the output from the energy is poor.
Testo 922 advantages:
Note: This meter uses a sensor to start up. Check the Brochure for available probes and accessories.
