You get the Thermocouples from Eric Svendson at
er...@erols.com (great guy)
The Temp data logger I use is an Omega, Eric can identify the correct model.
The software is Artisan. You get that here:

I suggest you roast without this for a month. and learn the roaster.
The guys at Sweet Marias can help you get it down.
You will be happy with the roaster, I have a buddy that owns a coffee
shop where they roast their own, and the Quest does a great job. Be
forewarned, do not leave the Quest alone. It is not UL certified and
it will burn your house down. On several occasions I have had the
temps north of 700 degrees. No temp shutoffs on this baby.
