How to recalibrate
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.

  1. Run warm water between 88-98F into a container deep enough to immerse both thermometers.
  2. Place thermometers in the water, check temperature readings once they have stabilized.
  3. If your new thermometer is not reading at the same temp as the medical thermometer, locate the nut found under the dial head.
  4. Using a wrench, turn the nut clockwise or counterclockwise as needed until the needle reads the same temperature as the medical thermometer.
  5. Repeat this process as needed.

Tall Thermometer

I love how this thermometer is long enough to fit in my BIG pot and give me an accurate reading.

Easy to read and practical

Tel-Tru is as An eady to read thermometer with a good size face and numbers. Also the pan clip/support allows you to free your hands for other tasks while the milk is warming up.

Easy to read and is accurate

Once we calibrated the thermometer, it has worked great and is accurate! I love how it sits on the side of the pan and is easy to read.

Tel-Tru Thermometer

Thermometer reads 3 degrees F too high, so this needs to be subtracted from readings while making cheese. Otherwise, it works fine. A cheese thermometer that reads in a narrower range (up to about 120F) would be better for making hard cheeses.

Not Going to Break

After having had a series of glass floating thermometers for making cheese, I took the dive and switched to the metal instant-read thermometer. Originally I was concerned that it would not clip on to the variety of pans which I use for cheese making - but I needn't have worried. It clips on three different pans, gives a quick read (and accurate, based on two other thermometers) and was easy to read as well. I can see I'll be using this unit for years to come in my cheesemaking.
