Extech Digital Psychrometer Kit

Description

This versatile instrument simultaneously displays percent RH and temperature along with dew point, wet bulb, or probe temperature. The instrument also calculates T1-T2 differential (air temperature minus external probe temperature) using the temperature probe and T2-dew point. Other features include switchable degree F/ degree C temperature units, data hold to freeze the current reading on the display, max/min readings, and auto power off. The unique sensor cap design twists closed to ensure protection during storage. Kit includes digital psychrometer, 2 AAA batteries, temperature probe, 33 percent and 75 percent calibration bottles, and a carrying case. Specifications: Range: Humidity, 10 percent to 90 percent RH; Temperature (Internal), -4 degree F to 122 degree F (-20 degree C to 50 degree C); Temperature (External), -4 degree F to 158 degree F (-20 degree C to 70 degree C); Dew Point, -90.4 degree F to 122 degree F (-68.0 degree C to 49.9 degree C); Wet Bulb, -6.9 degree F to 122 degree F (-21.6 degree C to 49.9 degree C). Maximum Resolution: Humidity, 0.1 percent RH; Temperature (Internal and External), 0.1 degree. Basic Accuracy: Humidity, +/- 3 percent RH; Temperature (Internal and External), +/- 1 degree F or +/- 0.6 degree C.
