Extech RH300 Digital Psychrometer, Humidity (RH), Air Temperature, Dew Point & Wet Bulb Meter

Extech RH300 Digital Psychrometer, Humidity (RH), Air Temperature, Dew Point & Wet Bulb Meter

• Extech RH300 humidity meter with dew point
• Simultaneous display of %RH, temperature and dew point or wet bulb or probe temperature
• Wet bulb measurements without slinging
• Calculates T1-T2 differential (air temperature minus external probe temperature) using optional probe (TP890) and T-2 dew point
• Unique sensor cap design twists to closed position for protection during storage

Compact meter is ideal for field applications - it displays relative humidity and temperature simultaneously, and dew point or wet bulb or probe temperature on a large LCD. Features include a choice of readings in degF or degC, Min/Max, data hold, and auto power off. Unique sensor cap closes to protect the sensor during storage. Advanced features include the calculation of T1-T2 temperature differential with external temperature probe 37803-18 (sold separately). Unique sensor cap closes to protect the sensor during storage. Meter can be calibrated in the field using optional RH calibration standard salts. Order meter only or the complete thermohygrometer kit. 37803-10 includes two AAA batteries. Optional thermistor probe lets you calculate T1 - T2
