Digital Psychrometer

This is an excellent compromise between less accurate, "consumer" grade digital thermohygrometers and highly accurate but complicated analog sling psychrometers. Measures humidity from 0 to 100% rH, with accuracy of ±3%. Measures temperature from -4 to 122 °F (-20 to 50 °C) with accuracy of ±1 °F (±.6 °C). Resolution is .1 °F, .1 °C, and .1% rH. Data functions include Temperature, Humidity, Dew Point and Wet Bulb Temperatures, "Min/Max" and Data Hold settings. Features a large, easy-to-read backlit display. Magnetic backing allows for hands-free use, and the probe cover also functions as an extension for taking readings in hard-to-reach places. Requires 2 CR2032 "coin"-style batteries (included).
