Comparable Product:


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. Because of its 38" telescoping probe, measurements are easier to take in the prime location -- in the duct, near the evaporator. So HVACR pros know the results aren't affected by duct leaks or outside air temperature.
