Rubbermaid Commercial Products Thermometer, Classic Large Mechanical Dial, Chrome, Extreme Temperature Range for Use in Refrigerator/Freezer/Cooler/Fridge

I set my oven at 300 degrees and put this thermometer in after it preheated to test its accuracy.It was spot on at 300 exactly a perfect 300 it can't get any better than perfect. If you are looking for accuracy this is the cats meow.

I couldn't tell how far my oven temperature was until I got this. I calibrated it in an air fryer and found my oven was >10F off at times. This is critical to have for baking.

Refrigerator / Freezer Thermometer. Attached to this review is a picture of the info on the back of the package.2025 review: The Refrigerator / Freezer Thermometer works but I'm not sure how accurate it is, since I don't have calibrated scientific equipment. It is "good enough" I think.My idea was to put one unit in the fridge, one in the freezer, and one in my basement freezer. I now have 3 Rubbermaid Refrigerator / Freezer Thermometers. One I got back in 2018, and two more in 2025. The one from 2018 still works fine. Of the two new ones, one of them reads the same as my 2018 model, the other is two degrees F higher. I have no way of telling which readout is more accurate.There is a difference between Accuracy and Precision. Accuracy is how close to the truth it is. Precision is how close to the same result something reads each time, not considering the truth.For example, a thermometer that reads the exact temperature would be Accurate. A thermometer that reads a few degrees off, but by the same amount each time, would be Precise.Lastly I think it would be great if someone would do a test of all major thermometers, using calibrated scientific equipment.

small and convenient to use in my freezer.

As good as it gets.

very accurate

This little thermometer showed me why oven cooked meals were always off. My over is about 15 degrees cooler than the temperature it's internal system says.Now with this tool my oven cooking is great.

Bought this to check, and adjust if necessary, our new oven. However, the needle moves so slowly that I could never tell if it had settled out or was still slowly moving. I'm talking 15 to 30 minutes waiting. Same thing going down in oven temperature. I gave up and ordered another brand hoping for more needle responsiveness. Also had a digital probe in the oven and the two never agreed.
