To assist HVACR professionals in getting the proper measurements, Fieldpiece engineered this in duct psychrometer head to take measurements in the duct where they are supposed to be taken -- near the evaporator! So HVACR professionals can trust the results for tests like temperature splits, target evaporator exit temperture, target superheat, and CheckMe!® because measurements are taken without the interference of outside air temp or leaks in the duct work.
Plus, the ARH5 can make hustling from condensor, to attic, and back again to take indoor wet bulb and charge a system, a thing of the past! When attached to a wireless transmitter, ARH5 measurements can be sent wirelessly to any Fieldpiece wireless meter (HG3, LT17AW, EH4W) from anywhere on the job site. So results like indoor wet bulb, can be read in real-time on your wireless meter from up to 100' away.
