Review on Track and Monitor Food Safety with VICI TM803 Digital Fridge Freezer Thermometer by Jim Viswanadham

Be sure to follow the instructions for setting alarms, switching between sensors etc. The buttons are not intuitive but they work quite well good good (I also compared it with another thermometer). There is a magnet on the back so you can hang it next to the freezer. The wire is thin enough to provide a vacuum seal for my chest freezer, but thick enough to dent the rubber gasket itself. Since this is a chest freezer, the weight of the door covers everything well.
