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.

Best thermometer

I ordered a second thermometer because the Tel-Tru is the most acurite of all. I sometimes do more than one batch of cheese. I would recommend it.

First use

The clip failed to balance the thermometer and it fell out of the pot Lesson learned the hard way. It broke

Works So Far

I bought my Tel-Tru thermometer a couple months ago and have made ricotta, mozzarella, yogurt, and a couple other things using it so far. Overall, I'm happy and have had a consistently similar temperature reading when comparing it to my other digital and non-digital thermometers. I like that you can purchase it in two lengths and the clip has so far held fine on my pot. The 12" length is a bit too long for my pot, but the face is not adjustable height wise on the clip (that I can figure out--I'll edit review if I find it to adjustable), so make sure you buy the right size. Otherwise, it seems accurate, the face is nice and big, and it's never botched a bath of anything yet!

Best effort in accurate temperature control!

I invested in two of these thermometers so that I can manage cheese and bath temperature accurately. I have a temperature in my Anova bath on the sous vide, then a constant culture or curd temperature with one thermometer. Then adding so much water at said temperature to cook the curds at will accurately with my second thermometer. Two thermometers is my saving grace! They are accurate instantly and reliability is paramount!
