Fieldpiece - The PRH2 is an economical, stand-alone psychrometer that measures wet bulb, %RH, dew point and dry bulb temperatures, all in the convenience of a pocket tool. This parts grabber has a strong magnet with a clawed hand and a 24" extension to grab out of reach parts. The claw and magnet hook onto the parts for that extra force needed to get them moving out from under a unit. Sleek chrome finish and pocket clip stay securely in pocket when not in use.
