Query: Great analog thermometer

I ordered 3 of these for general purpose use in the kitchen and around the house. The sleeve comes with a built-in calibration wrench which makes calibration simple and easy. Just make an ice/water slurry and stick the thermometer in. Once the needle settles, calibrate it to the 32 degree mark. Simple and easy. They arrive accurately calibrated.
