Sper Scientific 800026 Additional Temperature Sensor

Read the temperature inside an environmental chamber or clean room without opening the door. Mount the sensor outdoors (the sensor is weatherproof), in green houses, warehouses, air ducts and other hard to reach places and continuously monitor their ambient temperature from a remote location. The sensor broadcasts the temperature to the monitor from up to 100' (30M) away (in an open area) via a wireless RF signal. The monitor displays either the local or remote temperatures in °C or °F, has min/max recall, audible and visual alarms, and indicates when the batteries are low in both the sensors and monitor. Each monitor comes with 1 temperature sensor with bench stand and wall mount and batteries (2 x AA + 2 x AAA) which last about 1 year. The monitor will read up to 3 temperature sensors, with the additional sensors sold separately.
