Egads, I am a bit confused due to the lengthiness of the instructions, not to mention all the options.

I am assuming the following part is what you were suggesting for me? 2X for quantity to measure BT and ET? Crazy how the fittings cost more than the thermocouples!

Thermocouple Adaptor for
Quest Roaster – Direct
Replacement for stock
thermometer $40

Anyhoo, I shot him and email just to clarify. Let me know if I'm looking at the right part. Thanks!

Also very confused by the following directions, assuming I have the right part...

Slide the thermocouple in place until the tip (inside the roaster) is about 1/8” away from
the closest drum supporting strut. Rotate the drum by hand to ENSURE that any strut
does not contact the thermocouple. The thermocouple should extend into the drum as
far as possible WITHOUT contacting the strut. This should not be considered a trivial
With the thermocouple properly positioned, apply a small dab of nail polish (or
equivalent) to the thermocouple probe where it exits the 7/16” gland nut on the outside
of the roaster. Snug up the 7/16” nut – maybe 1/2 turn past finger tight while orientating
the thermocouple in the desired position

What is the 7/16" gland nut? The whole time we're referring to 1/8"... and what does he mean by it "exiting" the gland nut? Isn't the thermocouple being inserted into the roaster?

And he also mentions a "1/2 turn past finger tight". So I assume I need some tool to turn it 180 degrees once my fingers no longer do the trick?

Also what is the point of nail polish? And where exactly do I apply it?

I am so sorry for the confusion, and thank you for all the help!

Thank you for the informative response!

Just got the necessary parts, but I'm stumped on how to thread the new K-type thermocouple probes to the Quest. In the pictures, you seem to have some kinda nut that sealed the probe quite nicely!

BTW I have the probe depicted in page 3 of 4 with the phone line coil thingy.

Is there a tutorial for this available somewhere? Thanks again!

Thank you Danny for the informative response!

1. You mentioned J-type thermocouples. What is the advantage of J over K? Which would ya recommend?

2. As for the BBQ iCelsius app, why would I need wireless portability of Phidget? Do some people use Roastmaster for shop roasters as well? Sorry, I thought the Roastmaster was tailored for Quest M3 and Behmor. And what do you mean by limited temp range? I don't think you need more than 500 F, no?

3. I apologize for not clarifying in my original post that I have a Quest M3 at home. I will also have access to a 2K Ambex and 5K Diedrich, so if Roastmaster is applicable on other roasters, that would work out fantastic! You mentioned that in addition to everything listed above, I would also need a Phidget SBC3. Do you have a link for this as well? Thanks!

4. I am also planning on purchasing a laptop as well, so should I just forgo the Phidget SBC3 if I don't need it?

Thank you once again for all the help with my setup!

I just tried to order the parts to get started, but it appears the 4 Port Temp Sensor indicated in the following link is no longer. Do you have any suggestions?

So I'm planning on purchasing an iPad, 4 Port Temp Sensor, Acrylic Enclosure, and K Type Thermocouple. Is this all? As noted above, the 4 Port Temp Sensor is not available anymore... or at least the link is leading to an antiquated page.

PS: I'm a complete newb, and I'm not much of an engineer-minded person, so I apologize in advance if I'm asking terribly basic questions. Appreciate all the help I can get.
