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.

Seems good overall not sure how accurate it is checked it against several other thermometers

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!

Mediocre thermometer

I've used this thermomer for several years now and can't say that it'll be the most convenient thermometer for most folks. First of all, the clip doesn't really work very well. It doesn't provide enough of a tight fit to the side of the pot to allow it to be clipped on and left unattended. Secondly, although it offers the ability to be recalibrated, I've found that even with the most careful and delicate handling recalibration is frequently required. Though it's not very difficult to recalibrate, I believe most folks will find it an inconvenient task that, especially for cheesemaking, you'll want to perform frequently to ensure your temp readings are accurate. Over time and many required recalibrations, the nut that you turn to recalibrate has become easier to turn making extremely careful handling critical to preserving accuracy (all thermometers should be handled carefully, but this one's off the charts.) For someone devoted to the technical particulars this thermometer requires it's not a bad unit for the money. If you're after a highly accurate thermometer that you can consistently rely on the accuracy of without constant recalibration (and which will cost more) this isn't what you should buy.

This thermometer is awesome…especially if you are using it in a large pot of milk! I like the longer length to get a more accurate reading of the milk.

I really like this thermometer. It works well, and it is actually made in the USA, I didn't know that when I purchased it, this was a bonus. I haven't had it very long, but it seems as though it will last a long time.
