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 inefficiently, but with the SRH3 it's easier to ensure units are running at their maximum efficiency.
