Track and Monitor Food Safety with VICI TM803 Digital Fridge Freezer Thermometer Review

On the second day of use, the temperature says more than 120 degrees, although the aquarium water was actually 78 degrees. The supposed probe is not really waterproof.

The only problem I have is that the numbers are difficult to read. To read them I have to go 12 to 18 inches. Otherwise I like this device. It has a very long cord, so setting the temperature measuring point in the right place in the freezer is not a problem.

Handy for vertical freezing to keep an eye on the internal temperature. The flat cable makes it easy to route under the door seal without causing frost or temperature loss. Also fairly accurate compared to my calibrated thermocouple.

The freezer I wanted is in the basement. The alarm wasn't loud enough to be heard upstairs and it rang too infrequently to be sure it would be heard if you rushed down to the basement to get something. I didn't measure, but it seemed to me that the noises were heard at intervals of a minute or two.

Block works as advertised so far with no issues. The controls are pretty easy to use. It comes with about five or six feet of probe cord, which you should stow away if you're a fan of neatness. The only problem with this is the supplied adhesive to attach the device to the wall, which doesn't seem to work very well. I replaced the Gorilla Ribbon but it might be too raw for some installs.

When the temperature rises above the value you set, it beeps 5 times. Beeps will be repeated every one to two minutes until the temperature is back below the set point. It's a good balance to the constant alarm, as it's not too annoying if you open the door a bit while you're storing or cleaning up the freezer. .Also has a MIN/MAX function that allows you to view the upper and lower set points for the freezer on/off cycle.

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.
