I've been smoking with the WSM for about 20 years now. I've never been happy with my thermometers. Actually, I've never been happy with thermometers whether for the WMS or otherwise.
For example, I've got a fairly new Therma-Pen instant read and a new Thermo Smoke. The other day, I had a brisket in the oven and the oven temp said it was 350*. One of those little analog oven thermometers said it was about 345*. But my Thermo Smoke said it was only 320*.
I put the analog and the Thermo smoke in my Breville toaster oven, set at 350*. The toaster oven beeped that it reached 350* when the analog said it was only 320* and the Smoke said it was 280*
I guess the only real way to test them is to use boiling water? Because I'm pretty much at sea level and it should be 212*?
