Wireless Humidity/Temperature Monitor Set, with NIST Certification

Monitor relative humidity and temperature inside an environmental chamber or clean room without opening the door. Place the weatherproof sensor outdoors, in green houses, warehouses, air ducts and other hard to reach places and continuously monitor ambient relative humidity and temperature from a remote location.The wireless sensors broadcast to the monitor from up to 100 feet 30 M away without obstructions, using a wireless RF signal. The monitor displays the local and remote temperatures in C or F, recalls min/max on both, and indicates when the batteries are low in both the sensors and monitor. It also displays user adjustable, audible and visible, Hi / Lo Alarms, on both temperature and relative humidity, for the base unit and the remote sensors.The monitor comes with one sensor that also displays local relative humidity and temperature and stands on a bench or wall mounts. Supplied with 2 x AAA batteries for the monitor and 2 x AA batteries for the sensor.
