Fieldpiece PRH2: Pocket Psychrometer
Description
PRH2 Fieldpiece Pocket Psychrometer with WB, DB, RH% & DP
For real-time, instant readings techs use every day, the PRH2 is a must-have for every HVACR professional. Small enough to clip to your pocket like a pen, it's the tool you reach for on walk-around testing, commissioning, and any time you need quick psychrometric readings without lugging out the full kit.
The PRH2 measures wet bulb, dry bulb, dew point and relative humidity, shown on a backlit dual display — measurements can be taken either in the duct or while walking around. The slim 2" tip inserts easily into ductwork and grilles, and the twist cap protects the sensors when not in use so it survives rattling around in a tool bag.
Runs on a single AA battery lasting up to 100 hours. Hold, min and max functions let you lock in readings for recording, and auto power-off can be disabled when you need continuous monitoring.
