Nithing Fridge Freezer Thermometer Max/Min Memory High & Low Temperature Alarms Settings with LED Indicator Digital Refrigeration Thermometer with Magnetic,Stander

I am using this to monitor my vintage kegerator temp. Probe was thin and easy to slip into rear of kegerator. Screen is large and easy to read. Would be easy to surface mount with some double sided tape.

These work great - just saved our entire freezers worth of food. Thank goodness we installed these!

Unit seems to work well. However, it seems to only work in Celsius. Can't figure out how to change it to Fahrenheit. That's not a real problem for me.Service was very good. In fact, arrived a day earlier than projected.

So someone in our family left our basement freezer door open. All our frozen meats and soups and lasagnas and whatnot all thawed and came up to room temp for more than 48hours. High $ loss. I bought this "alarm" to make sure we notice if this ever happens again.This is a decent temperature monitor with a remote probe. It has an alarm function that you set a range of acceptable temps. Outside this range, the alarm is triggered. So for example you can set it to -20F to 25F and if your freezer gets warmer than 25F or colder than -20F it beeps. You can set this range from like -58F to 200F.The problem though is that the alarm is pretty quiet. You are not going to hear it two rooms away. Maybe even not one room away. Also it only beeps 5 times, then silent for 1 minute 13 seconds and 5 more beeps and so on. So you could be walking past your freezer during the 73 seconds of silence and not know you had an alarm.I'm going to look for a louder alarm. This one is fine for monitoring your temps, but don't expect to hear the alarm if say you have your freezer out in the garage...

Great thermometers easy to use.

Purchased two of these alarm thermometers.Got this mainly for the gas water heater because the pilot goes out occasionally, usually during windy days, and the wife does not like cold showers. On the water heater I tied the outdoor sensor to the side of the brass pressure relief valve, which has good thermal conductivity to the hot water tank, and set the max/min values to 140F/107F. During normal usage (long shower) the temperature only drops down to about 115F. If the pilot goes out the temperature drops below the minimum setting and the alarm sounds. Perfect!Put the second one in the garage fridge/freezer because the GFIC that its on gets tripped once in awhile, usually after working with power tools in the garage or yard. Sometimes that happens right when turning the tool off so I don’t notice.Thermometers are in the garage but the alarms are loud enough to be heard in the house at night when there are no other competing sounds. Units have magnets on the back for easy mounting and came with two batteries each. These units are a nice inexpensive solution to avoiding cold showers and melted ice cream.

My teen and I set these up and right away I knew they were being returned. The 2 never displayed the same temps sitting next to each other. The room was about 80 degrees and A said 85 and B said 83 ok not too far off from each other... I put them in 2 different freezers that have a simple temp gauge that says they are 0 degrees. 24 hours later my upright says is is -2.7 room temp 77.6 (this is close) but the chest freezer says room is 76.5 and inside the freezer is -15 (this is absurd) I had to turn the alarms off as they kept going off. The upright was -9.6 last night and I set the alarm for -9.4 since I could not get it to be -10 to 10. I will let them acclimate another day but I doubt I will be keeping them.

Works great, easy to use
