Fieldpiece SRH3 In-Duct Digital Psychrometer Telescoping Wand, 0 to 100 % RH Humidity, +/-2.5 % Accuracy, 0 to 122 deg F, 2.6 in W

The SRH3 in-duct psychrometer is a great tool to properly charge fixed restrictor systems by quickly determining the target superheat and to help determine optimum airflow across the evaporator with a target evaporator exit temperature 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 near the evaporator! The 38 in 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 in-duct 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 in efficiently, but with the SRH3 it's easier to ensure units are running at their maximum efficiency.
