## Questions & Answers

**Q: how can i use this**
A: When you go in to the customers house turn on The A/C take WB (wet bulb) reading at the return air grill then go outside and take a dry bulb measurement at condensing unit or heat pump use your measurements with your refrigerant gauges. And calculate your subcooling or superheat depending on weather you have a TXV or not, I just enter the values in to my SMAN4 gauges and it calculates it for me the I either add or remove (reclaim) refrigerant to reach my subcooling or superheat or you can type in Fieldpiece PRH2 in to You Tube and watch a video on how to use it

**Q: Tip diameter and lenght? For measuring WB temp of air entering and leaving evaporator?**
A: 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. Portable enough to clip into a pocket, the PRH2 is great for walk-around testing, and the pen-like psychrometer features a slim, 2” long tip to take measurements easily inside ductwork.

The PRH2 has a bright backlight so it’s easy to read in dark areas and runs on a single AA-battery that lasts up to 100 hours.

**Q: In what way is this device a psychomotor?**
A: It's not a psychomotor, it's a psychrometer.

**Q: Can this be calibratesmf by the owner on his own?**
A: Yes

## Customer Reviews

### ⭐⭐⭐⭐⭐ A Must!!!
*by A***N on February 18, 2026*

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

### ⭐⭐⭐⭐⭐ Small and functional
*by K***N on January 17, 2026*

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

### ⭐⭐⭐⭐⭐ Easy to use, nice size, not fragile.
*by H***E on November 23, 2020*

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.
