My old unit died. I am looking for a replacement. It had a thermocouple probe and maxed out about 567*F. had timer temp alarm etc. I also used it for BBQ and meat smoking. I see a lot of units that only go to 275- 400* I am seeing temps in excess of 600*. does anyone have a recommendation for an affordable unit.

How about the TC-4 coffee roaster arduino shield. It supports up to 4 thermocouples and will monitor/log your entire roast profile to your computer. A fully assembled, tested, and programmed unit can be had for $89. If you are familiar with the arduino microcontroller platform and you can solder it can be bought in a kit for much cheaper.

If you want affordable, check out the multimeters listed on the Sears website. At least 3 listed with thermocouples good for up to 1400/F. About 20 bucks for the cheapest model. No complaints on the one I have.

I am not familiar with the unit. But is sounds Interesting. I have found cheap Chinese type K Thernocouples since I posted this and have sort of vaguely considered using a Micro controller. I do have soldering skills. so where would I find one of these Arduino units. I have bought a digital timer and a new probe for a digital thermometer that I have. I recently had to recalibrate it.

I Had not considered that option. I am aware of the capability but have not priced one in many years. They used to be expensive at least for the units with the Thermocouple. Does yours use a type K as I have several+ I have the one from my dead unit but without documentation I am not sure what it is. possibly type N. as it uses a mini stereo jack. George

Sears manual says it uses Type K, which would be the most common. You just have to pay attention to polarity with the junctions if you're changing connectors. Also, I just found a package insert from my meter, and max temp is listed @ 500/F. No idea why the manual says otherwise @ 1400/F. My maximum roast temps usually go no higher than 460/F. My old Fluke had a type K and the range on that went up to 1400 on a single temp setting.

Interesting. do you know of anyone who uses the output to control the temp, I have been considering installing a thermostat as with my new roaster I am over roasted at 3 minfrom 1st crack and it sounds like 2nd crack did with my old roaster. { they are both showtime chicken rotisseries] when I first started to experiment with these units too hot didn't occur to me. as the issue was get it hot enough... Thanks for the input.
