WSG Wireless Temperature Sensors with External Probes are designed to work exclusively with the Sensaphone WSG30. This sensor circuitry includes a built-in radio transmitter. The sensors attach to a remote temperature probe so that temperature measurements can be made in a refrigerator, freezer or other harsh environments. The sensor is available in two temperature ranges; -20° to 115°F or -121° to 115°F. It comes with two AA alkaline batteries which will power the sensor for up to two years. An optional plug-in power supply is also available in which case the batteries become a backup if the main AC power fails.
