I would suggest, from my experience, to be very careful using the digital thermometer. It could be that I am jinxed or something, but after trying 5 different digital thermometers that cost me from $20.00 to over $100.00, every one failed, a couple of times with near disaster results. I find that a bi-metal round thermometer is much more reliable year after year.

Were these through the side as pictured or in the top where they get steam? I have used a waterproof one for many years.

Default Side mount

There is a bushing welded to the draw off port. The thermometer threads into it should be no issue with steam or moisture

I agree. Yours should be fine. I have seen unsealed ones not last very long in the steam.

Wiam,

Most of the digital thermometers were over the side ones and one used to check the temperature of syrup before caning. They all failed. Just my experience

And here I thought it was only me who keep making the same mistake.

Many people equate readability with accuracy. That isn't always the case.

Over the range of -50 to +300, with a +/-1% accuracy, your inherent instrument error is +/- 3.5 deg F, even if it is calibrated correctly. Generally you'll find it is likely to do better than that, but those are the specs.

+/- 1% is pretty typical for inexpensive thermistor-type thermometers. For thermocouple-type thermometers it can be even more.

When you first start to boil with sap, just check carefully to make sure that it is close to 212 deg F or just a tad more. And double-check your density with a good calibrated hydrometer (or refractometer...but those have their own issues).

As far as digital or analog goes...we use both. Analog never run out of batteries though.
