I've always had permanent thermometers on our 2 fridges and chest freezer.
Recently I decided to replace some as they looked tired. I poked around in TEMU and found one claiming to be suitable for fridges.

I placed my 2 new $2.70 thermometers into the bar fridge freezer with their probes physically bound to my food quality thermometer probe and here is the result...
