Can I use a Sensaphone to monitor the temperature in a refrigerator or freezer?

Yes. Any model Sensaphone can monitor temperature inside a refrigerator or freezer and call you when the temperature goes outside of your pre-programmed acceptable range. You will need one temperature probe for each section to be monitored (example: 1 probe for refrigerator portion and 1 probe for freezer portion). For all Sensaphone models except the SCADA and Skymetry, you would use part number FGD-0101 (2.8K Weatherproof Temperature Probe).
