Precision Diagnostic Instruments: In-Duct Diagnostic Psychrometer
January 21, 2013
Designed to take accurate measurements of humidity and temperature from the most difficult to reach places is the DP-110 in-duct digital psychrometer. The 6-inch flex neck allows technicians to position the sensor in ducts or plenums. The psychrometer can measure temperature, percent rh, and wet bulb/dry bulb, allowing technicians to measure wet bulb and dry bulb temperatures directly before and after the evaporator coil to determine target evaporator exit temperature, and the indoor wet bulb and outdoor dry bulb temperatures to determine target superheat. Features of the DP-110 include maximum, minimum, and hold functions; and backlight and auto power off.
