The Fieldpiece SRH2 Diagnostic Psychrometer is an easy to use hand-held diagnostic instrument that performs the normal functions of a digital psychrometer plus it calculates critical air conditioning system targets from psychometric measurements.
  • Measures temperature (DB) and %relative humidity (%RH)
  • Calculates wet bulb (WB) and dew point (DP)
  • Calculates Target Superheat (TSH)
  • Calculates Target Evaporator Exit Temp (TEET) (aka - delta T, temp split)
  • Only digital psychrometer that takes measurements using an electronic sensor (NTC) or k-type thermocouples (T/C)
