Quest-Compatible Thermocouple Probe 38mm

We had a new thermometer probe made that is compatible with the Quest M3s and M6 coffee roasters (as well as other roast applications too). It features a 38 mm long probe with threaded M8 metric which will work with the Quest models.

We opted for a slender probe tip here, only 2 mm, which makes it very sensitive to temperature change. It’s a bit delicate, but will respond quickly to changes … and that’s what we wanted! The cable connects to a standard mini plug that will work with your standard thermometers, including the types we sell.

The cable is a rather short 3 feet, but we keep finding ourselves coiling up longer cables so wanted to opt for a short one here. This isn’t a high-end Fluke quality probe, but it’s also not $50 ! For that kind of money,  you can buy 6 of these to last a long, long time.

We'll also note that in some positions the nut on this probe can prevent the bean door from opening fully. Rotating the nut slightly works for us, so it's not been an issue (but it's worth mentioning). You can always add another nut as a spacer.
