Tel-Tru Thermometer

How to re-calibrate: Since the cheese making process happens at temperatures similar to our healthy body temperatures, a good quality medical thermometer can be used to calibrate your thermometer. Run warm water between 88°-98° F into a container deep enough to immerse both thermometers. Place thermometers in the water, check temperature readings once they have stabilized. If your new thermometer is not reading at the same temp as the medical thermometer, locate the nut found under the dial head. Using a wrench, turn the nut clockwise or counterclockwise as needed until the needle reads the same temperature as the medical thermometer. Repeat this process occasionally to maintain an accurate reading on your thermometer.
