Accuracy all depends on the quality of the non-contact sensor whereas an analog temp sensor depends on a bi-metallic strip. My Accurite seems pretty close but then all one needs to be concerned with is how close to freezing is the compartment.
:h
OP isn't talking about IR guns here (no contact) and most old school analog "bi-metallic" thermometers now days are pretty cheaply built and not very plentiful to find.
OP is talking about using a WIRELESS (two pieces, a remote transmitter which goes in the fridge and the display unit which can sit on a counter and no wires connecting the two parts) thermometer to monitor the inside temps of a fridge.
I am not a fan of wireless thermometers for this purpose, the constant near freezing to sub freezing temps found in fridge/freezers quickly zaps the life out of the batteries in the remote sensor.
This can cause inaccuracies in readings and tends to zap battery life considerably.
I prefer to use indoor/outdoor WIRED type which have a wired remote probe. I simply slip the remote wire in between the door seal in a spot which will not interfere with getting things in and out of the fridge (think HINGE SIDE of the door).
Then tie or stick probe to one of the shelves.
The batteries are now outside of the fridge and are not affected by the near freezing or sub freezing temps inside the fridge..
Wired are also much more reliable, should not have any issue finding wired types for $5-$20..
