Fieldpiece PRH2 Digital Pocket Psychrometer for HVAC

Works just like it should I've been in the field for 40 years couldn't ask for anything more accurate

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

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

The PRH2 is a handy tool and I've used it numerous times already in the short time I've had it to determine Wet bulb for calculation of target superheat. The size is just right and I keep it in my Veto TP4 when not in use. I wanted to give it 5 stars but the plastic threading of the cap and the unit don't seam to match very well. In fact if your not careful you can easily, very easily cross thread it. So be careful. I can get the cap to screw on but it's less than a full turn, which doesn't seem natural. If this cap wasn't able to be secured then it would be on its way back. So to summarize I really like this tool, it works well and it will remain in my bag.

As an hvac tech, this is a much needed tool and the size makes taking it with you so much easier. It is made of metal and has a screw on cap. It will lay on top of a stat while work is being performed. It does take slightly longer to adjust (about a min) than my exetech but the size makes the issue worth putting up with.

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.

Excellent for taking wet / dry bulb temperatures

Awesome product, very accurate, takes a minute or so to settle on target, but great value for the price. I use this on every call, will buy another.

Fast delivery and easy to use . Picture just like the real deal , compact tool perfect for techs

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.

I’m an hvac tech- and I use it for proper AC setup (to get temp and wet bulb readings ).

Works Good :)

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