Fieldpiece PRH2 Digital Psychomotor

Very accurate and works great while being able to put in your pocket

Use this instrument daily for spot checking our wired system transmitters in 90% + humidity environments....it's good for a for a fast check.Most manufacturers including Fieldpiece claim +/- 5% accuracy at this range and it is proving well with in that range and for HVAC applications I think most Techs would be pleased with the performance.Before purchase I read a review regarding the threaded cap and potential failure - here's what happened with mine...when I received the product in factory packaging, the threaded bushing had slid to the cap top, I tapped it out and put a TINY drop of Krazy Glue on the outside of the bushing and reset it to the proper position inside the cap...it's perfect now.

Works great, needs several seconds to stabilize humidity and temp readings. The cap has not been as issue, it is plastic threads. If you don't cross thread the lug-nuts on a car, you won't have a problem with this unit. If you treat it like any other measuring instrument you have (don't drop it or treat it like a hand tool) it will last you quite a while. It has been used on several locations and been bouncing around the console of my truck with no issue to report.

As expected from other reviewers. Batteries last forever. Accurate. In tool bag, doesn't get beat up not sure if you want this in the bottom of your tool bag. Has it's own driver slot in my bag to keep from banging around.

Arrived much sooner than promised. As an HVAC technician, this is a valuable tool!
