Sensaphone WSG Wireless Ultra Low Temperature Sensor with External Probe

The FGD-WSG30-TEX85 is a wireless temperature sensor for ultra low temperatures that uses an external probe for monitoring temperatures inside freezers. The external probe can measure temperature from -121° to 115°F (-85° to 46°C) The probe can is placed inside the freezer and the transmitter stays in the room where it can have a better wireless range and normal operating temperature range. The sensor comes complete with two AA batteries which will power the sensor for approximately two years*. An optional AC Adapter is available in which case the batteries become a backup power source.
