Fieldpiece PRH2 Digital Psychomotor

The psychometer is must for any HVAC technician. Very content with my purchase.

Working great 👍. Looks sensitive so keep it safe, otherwise works great.

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.

Great tool, only reason for 4star is that I wish it was about one more inch longer for lined duct, and it should be made with metal, not plastic. Threads on protective cap are easily stripped. Measurements are accurate and as long as you have it in its own spot in your tool bag it should be ok.

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

Excellent for taking wet / dry bulb temperatures

Easy to use, and easier to read. Seems a quality product. The only complaint that I can think to have is the size. It is 3-4x the size around of a pen you would put in your pocket, and a little bit taller. I didn't take off a star because I had room for it in my tool bag, and it's small enough that room can easily be made in yours too. I'm happy with my purchase.

I use this regularly in my work as an HVAC service tech. It calculates indoor wet bulb and outdoor dry bulb accurately to calculate superheat for checking or charging an AC system. It is a good working tool but it has its flaws: - it doesn't clip into a shirt pocket - it is too long. - it is somewhat fragile. Do not twist the top on too hard or the insides will rotate in the case and damage it. Don't drop it. I've broken 2 in 5 years but I'm hard on tools. - it can be slow to register temperatures.

My favourite one I’ve owned so far. Not too bad for the price tag and it fits well in a tool bag, just have to make sure I don’t forget it somewhere with it being pocket sized.

Does exactly what it was expected to do. Sometimes the buttons don't respond though.

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 Good :)

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.
