SRH3 Fieldpiece In-Duct Diagnostic Psychrometer - Easy Target Superheat. In-duct Air Measurements Near the Evaporator. 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" 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.

Like all Fieldpiece products, the SRH3 digital psychrometer was engineering specifically for HVACR professionals. It contains the specific measurements and tests techs need, without any they don't. Because it automatically calculates target superheat and target evaporator exit temperature, PT charts and written math are a thing of the past. Plus the dual display with bright backlight, and rugged rubber boot with probe clips make sure the SRH3 is ready for any job.
