The SRH3 In Duct Psychrometer is a great tool to properly charge fixed resistor systems by quickly determining the target superheat, and to help verify evaporator performance with the evaporator split test. To assist HVACR professionals get the proper measurements, Fieldpiece engineered this in-duct psychrometer to take measurements in the duct where they are supposed to be taken, in the duct! Measures temperature, relative humidity and calculates wet bulb and dew point temperatures.
The 38" telescoping probe's laser etched ruling and flattened edges allows techs to locate proper measurement points within a duct, and ensures that the probe is properly aligned. With the quick sensor it's a snap to determine target superheat, and take target evaporator exit temperature tests.
Designed specifically for HVACR professionals, the SRH3 InDuct Diagnostic Psychrometer is a great tool to properly charge fixed restrictor systems. More than 70% of A/C units are improperly charged, and therefore running inefficiently, but with the SRH3 it's easier to ensure units are running at their maximum efficiency.
