I finally got a new thermometer today...old one is on the right, new on the left... Mighty big difference in readings!!
I thought I was doing fairly well keeping the temp up and the creosote to a minimum. Silly me.

I gave up and threw out my Rutland(s), they were never accurate for me either. I just go Infrared, super accurate. Hopefully that Imperials lasts you a while though, gotta be better than a Rutland.

Wow - off by 75 ::F that's quite a bit. Now the classic case ... which one is right, which one is wrong, and are they both wrong?

I'd be inclined to heat up your oven to say 350::F and then pop those guys in there and see which one you believe. That said, then that assumes that your oven is correct.

....the oven idea is a good one...but my oven temp knob is loose. A test like that wouldn't do any good anyway. LOL

Sounds like my life - sometimes it seems like more of my stuff is broken than is working. :eek:

I've got to correct my post about putting the stove pipe thermometers in an oven to check the accuracy/calibration. :oops: This has come up before and the bi-metallic coil is not fully touching the pipe and the thermometer is basically "vented" and losing heat all the time. The temperature reading (and the zones) are adjusted for this, so you can't put them in an oven to check them. I think they would always read too high when in the "test oven" because they are heated fully because they are in the oven and can never lose any heat.

This is true for a stove top thermometer as well. The best (only?) way to check is with an IR gun. Sorry for any confusion.
