Question on thermometer accuracy

[lakezumbro]

I just got a Maverick Wireless ET 732 thermometer for my birthday.  The probe inside the smoker registers about 50 degrees higher than the digital readout set on my Masterbuilt electric smoker.  Which do I believe?  Confusing-----

I would check the Maverick in boiling water to see if it's accurate.

I would boil test the ET 732 and as long as it read right I would believe t. The thermometers that come with the smoker are often off.

I would believe the Mav.  Digitals are much more acccurate than the bi-metal in the smoker.

My MES30 has "hot spots" in it. Over the chip pan is the hottest. Against the back wall is the second hottest. It seems that if I put the smoker probe on my ET-732 in the center or front of the cooking grate it more closely matches the MES30 temp readout. Even at that my MES reads 25 degrees hotter than the ET-732. I have used the boil test on the ET-732 and have double checked the ET-732 food probe with a Thermapen. I now set my smoker temps to the ET-732 instead of what the smoker thermometer reads.Food seems to come out better.

I'll be darned. I checked both probes in boiling water and they both read 212. Imagine that. That thing is accurate. Guess I'll have to recalibrate my cooker. Thanks for the advice.

I don't know if the MES can be recalibrated. If you find out how let me know mine is off 20*. I called Masterbuilt and they sent a new probe but I have not changed it out yet...JJ
