DP-110, In-Duct Digital Psychrometer

LD-150

The DP-110, In-Duct Digital Psychrometer, is designed to take accurate measurements of humidity and temperature from the most difficult to reach places. The convenient, 6" flex-neck allows technicians to position the sensor in ducts or plenums. Measure wet bulb and dry bulb temperatures directly before and after the evaporator coil to determine Target Evaporator Exit Temperature. Measure the indoor wet bulb and outdoor dry bulb to determine Target Superheat. The DP-110 takes all of the psychrometric measurements needed for any HVAC/R service.
