VWR FRIDGE/FREEZER THERMOMETER - VWR Digital Refrigerator/Freezer Thermometer with Alarm

My chest type freezer went out some time ago and I accidentally discovered it in time before my meat went bad.Since then I decided to try one of these to alert me to a problem.. Also I can just look at the digital display and see the temperature inside without lifting the door.. The warning alarm is not too loud but loud enough that you will notice..It has twin magnets that hold it in place on the outside of the freezer..

A little difficult to program but seems to work well.
