Replaced my shotty rutlands

those look allot easier to read

I just did the same thing. Got the same pair, also. Same stove too.

Deja vu...

I can't speak to every Condar thermometer . . . or the accuracy of my probe thermometer . . . but the Condar thermometer I have on my stove top is pretty close in terms of temp when I compare its temp to the temp reading I get from the IR heat gun.

I tried two Condar FlueGards (probe-type) and both were way off, in the oven test they were both reading ~1500-1700F (i.e. one was just below the 1600, the other was redlined) with the oven set to 450F. Took 'em both back and got my money back. Bought an IR thermometer from amazon (Raytek MT6) .... it's all I use now. I have a rutland magnetic like what you just got rid of, I find it's usually around 50-100F low on its reading. I keep it there more for my own amusement now.

"Anyone here have any experience with the accuracy of Condar products?"

I don't know how "accurate" they are, but I do know they are functional and dependable. I've had several Condar's in blaze kings, both as combustor probes and magnetic stack temp indicators, no problems. Condar has been producing them for 20 years or more.
Considering they are a metallic coil spring, extreme accuracy isnt going to be the strong suit. You can calibrate some of them by moving the position of the
pointer, if you have an accurate temp to calibrate too.
Really, I would only rely on any of them for suggestion rather than gospel.
Your picture of two thermometers showing two different temps proves the old saying "a man with one watch knows what time it is, with two he is never sure."
The Inferno you show in the picture looks very well thought out, I like it, easy to read is a good thing.

If the magnetic stack temp indicator falls off, you may have a problem (grin).

Checking the accuracy of any of these meters by putting them into the oven or into boiling waters is totally inappropriate. They are designed to read correctly with one side against a hot surface and the other side out in ambient air. Especially the probe style with the coil way outside the flue. Think about that for a minute, these are somewhat remote read instruments. Perhaps dipping the probe tip into boiling water would be better. I can blow on my condar probe meter and the needle will fall, they are highly dependent on the cooling effect of non-flue air to determine their reading.

I really like that inferno. Too bad local stores don't carry them. Did you folks mail order?
