- Temperature sensor
The WSG Wireless Ultra Low Temperature sensor with External Probe is designed to work exclusively with the Sensaphone WSG30. This sensor includes a built-in radio transmitter and a remote temperature probe so that temperature measurements can be made in a refrigerator, freezer or other harsh environments. The sensor 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 main AC power fails.
