The Cooper-Atkins SRH77A-E temperature and humidity thermistor is used to remotely monitor temperature and humidity in critical applications. The instrument reports temperature differential between two zones, relative humidity, and wet-bulb temperature. It has a temperature range of -40 to +300 degrees F/-40 to +150 degrees C with + or - 0.3 or 0.5% accuracy. The humidity range is 10 to 95% RH (90% RH non-condensing) with 0.1 degree or 1% resolution. The instrument has a sealed keypad that protects it from dust and moisture and a backlit display for reading in low-light areas. The auto-shut off features turns the instrument off after 15 minutes or can be disabled for readings that require a longer time. The instrument is powered by a 9V alkaline battery, which has a life span of approximately 90 hours. The set includes the SRH77A temperature/humidity thermistor reading instrument, a general purpose puncture probe, a pipe strap probe, a humidity probe, carrying case, and instructions.
