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.

I use to worry about my milk temperatures, was my old thermometer accurate? I saw loads of YouTube users using this one, so I purchased it. I checked the calibration in boiling water and it was spot on, it's long enough it just sits in my milk pot . And it enables me to take a reading in the depth of my milk, not just a top reading. We all know hot liquid rises after all . Now I'm a happy Cheese Nerd

Love this thermometer!

I was tempted to go with the shorter thermometer, but I am so glad I chose the longer one. The pan clip fits on all my larger kettles easily. The best part was the instructions for how to recalibrate the temperature on the thermometer. Easy, step by step instructions if I ever need them. I have an older Tel-Tru meat thermometer that can be recalibrated in the same way. Thank you!

12” thermometer

Good and accurate thermometer. I’ve measured it against boiling water as well as my digital thermometer and it’s accurate. I think my only issue would be that the clip is a little loose (at least on my pots). Good value for the price so far

Tel-tru thermometer

Very accurate thermometer. I’ve checked it with water coming to a boil and against my other mechanical and digital ones. It did crack but that was my fault for dropping it. I would say my only complaint (and it’s not a bad problem) is that it could be a little tighter spring that holds it on the pot
