Who to believe

I have an extra 4” Auber probe thermometer so I thought I’d see how well it would work for a cat thermometer in my Blaze king. Initially I was surprised to see the difference when I popped out the Condar and put the Auber in its place. So I then grabbed the oem, BK, which was similar to the Condar. So this morning before I loaded the stove again, which was basically a medium pile of coals. I pulled the Condar, gave the BK, its turn, then the Auber. All units had at least 5 minutes inside the hole. Both tests showed similar results with the Auber between 3-400 degrees below the coil gauges. I realize the BK doesn’t display temps however it looks similar to the Condar.

My guess would be the Auber being the most accurate.
The Condor is most likely reading far to high for the available heat making fuel in the firebox. This leads me to trusting the digital temp more,

@begreen and others are more versed in these.

It’s my belief after being through 2 condar and 1 new OEM gauge in the last couple months the coil gauges are wildly inaccurate as far as temperature goes anything past the inactive/active zone. I’ve had them wrap past 360 degrees rotation which would put cat temps around 3000 degrees plus. I don’t know what is going on with the gauges made recently but my original that came with my stove back in 2014 seemed much more accurate.

The 3000 degree statement assumes the coil is always linear (a 45 deg increase near the inactive/active zone is the same increase in F as a 45 deg near the end of the active zone).
I'm not sure that is an accurate assumption.

But I would tend to believe the Auber here.

Try them on a control. Boiling water in an open pot has a specific temperature for your altitude.

Is the probe depth identical between the analog and digital probes?

All probes are 4”
