Coming out of lurk mode:
My result doing this are similar...The thermocouple just behind and above the
clip on the left side of the roaster measures not much higher than 300 degrees
F. I usually roast 12 oz of beans. My laser temp probe at end of roast is
usually registering around 400 degrees at the end of a city plus roast.
I assume the air temp never gets to high because the beans are being roasted
primarily by radiant heat and the bean temp measurement is measuring the surface
temp and not the bean mass.
I just use the info as a gauge or comparison to previous roasts. I have tried
to use the air temp to gauge how long I open the door to drop the temp when I do
that. Truthfully, it's not so good an indicator as it doesn't seem to change
much. When I open the door and see it drop I know it's probably time to shut
the door again. Though the reading are pretty inconsistent.
So I'm pretty curious about this as well?

Now I am confused, not that this would be the first time. I have completely
cleaned the inside of my Behmor. I then mounted a thermocouple just behind the
clip the bean drum rides in on the left side of the roaster. It never measured
higher than 270 degrees F. I was roasting 13 oz of Guatemalan. I used a 1:45
preheat without the beans. Roaster measured up to 178 before I cut it off. The
beans roasted as well as I have been able to achieve with the Behmor. My laser
temp probe registered 380 when I cracked the door and pointed the laser at the
beans. Can someone explain the difference in the two temps?
Is this normal?
Is my temp probe faulty?how can I use this data?
