Humidity, Wet Bulb, Dew Point, Air Temperature Plus External Probe Temperature Measurements Extech RH300 Hygro-Thermometer Psychrometer

The RH300 is a compact meter that is ideal for field applications. Simultaneously displays relative humidity (10% to 90% RH), air temperature and dew point or wet bulb. Calculates T1-T2 differential (air temperature minus external probe temperature) using optional probe (TP890), and T2 minus dew point. Built-in protective sensor cap. Other features include Data Hold, Auto Power Off, and MAX/MIN reading. Complete with 2 AAA batteries.
