I have a couple of questions for you about this. Please see my post in the new Learning to roast on Quest M3 thread, which I think is a more appropriate place.

I noticed that no one has recommended the thermocouples that Coffee Shrub sells. Why not use these?

MCR said they couldnt provide any kind of concrete answer on which TCs work with the Quest, so that was a (understandable) disappointment.

I sent a PM with a link. I have them mounted in a drilled allen-head bolt with an inelegant stuffing of foil for insulation as the hole is 3mm or so. The braided stainless steel wire is held in place with twist ties. I don't find them too noisy, but you can judge for yourself. Here's a recent roast.
