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:

  • Quick and easy measurement of the differential temperature with pipe wrap probes
  • Also optionally available with radio probes for wireless measurement
  • Display of minimum and maximum measuring values
  • Immediate printing of measuring values via optional wireless printer
