I love this oven thermometer. It mounts, with a magnet, on the ""wall"" of the oven, so it's never hanging in the way or just about to be knocked down. I always know when my oven temperature is just right
This thermometer came out of the packaging reading 120�F (at 70�F room temperature). I have tested it in the oven and it reads 30-50�F too high (I tested it against an infrared thermometer). It hangs nicely, etc., but reads the wrong temperature
So I go to sur la table to replace the oxo oven thermometer which read my broil at 300, 200 degrees off mark. This gem was also inaccurate, but to a lesser degree around 50 degrees off. I am beginning to think you can't trust these as good measures of accuracy and I don't know how to calibrate it. I would hope one shouldn't have too. I have read that it should read at 212 when put in boiling water but I don't want to ruin it because the back part is open. I can't freeze it because it doesn't read temps less than 100 degrees. I am taking this back and getting the Cooper-Atkins Oven Thermometer that cooks illustrated has thoroughly tested so that I can stop doing this trial and error purchasing. BTW this site needs improvement the item I clicked on took me to a different model. On the website it looks like the store model has 7 5 star reviews, but when you click on it it isn't that great afterall. I wonder how many people you guys duped that way!
When I moved into my new home with all new appliances I thought I would replace my old oven thermometer. I took this one out of the package and turned on the oven to 450. The thermometer went to 300 and stopped there....and stayed at 300. Now I am shopping for a new thermometer.
