Portable Psychrometer Product Description
The RH300 Portable Psychrometers are compact humidity and temperature meters with built in probes that include wet bulbs and dew point measurements for quick assessment of air moisture content.  The portable psychrometers simultaneously display % relative humidity, temperature and dew point or web bulb or probe temperature.  The portable psychrometers were designed to allow wet bulb measurements without slinging.  The portable psychrometer calculates T1-T2 differential (air temperature minus external probe temperature) using the optional temperature probe and T2-dew point.

The RH300 Portable Psychrometers incorporate data hold and auto power off features.  The portable psychrometers also store minimum and maximum readings.  The Portable Psychrometer also allows the user to switch between F and C temperature units with 0.1 resolution.  The portable psychrometers incorporate a unique sensor cap design that twists to a closed for protection during storage.  The Portable Psychrometer comes with 2 AAA batteries.
