Relatively Inexpensive Thermocouple Reader

post #1 of 15
Thread Starter 
I just saw that the company I buy my thermocouples from (ThermoWorks....the makers of ThermaPen) is selling an realatively inexpensive thermocouple reader: the Mini MTC. It sells for $39 (without the thermocouple, which will run you an additional $25-$70). More exensive than the oven thermo's we typically use, but much more versitile and accurate than the cheap thermistor type probes used in those oven thermo's.

I use their air-type thermocouple that will pick up the temperature fluctuation of a gnat fart. Very fast and very accurate: THS-113-041

I also use their SmokeHouse probe. It is an 8" long probe with a 6' stainless armour enforced lead; built like a tank: THS-113-178

Thanks for the info...Look like some nice equipment......Might have to looking to getting one.......

not as fast acting but what I do is take T/C wire and twist the ends then weld the tip. For air temperature it works well enough, typically temperatures do not change that quickly except for the occasional gnat fart

Still gonna run ya about $75 with a probe. Will stick to the Acu-Rite for about $15 with probe.

Yep, and I have several of those as well. About the best bang for the buck. But since I already have several thermocouples, especially one with an 8" probe, it's nice to have something to read them without having to drag out the laptop (yes, even us Geeks have to unplug from time to time)

Where to buy Acu-Rite for $15.00?

I've looked for the "Acu-Rite" thermometer with probe on the internet and I haven't found any close to $15.00. The least I've found is $25.00 marked special sale from $39.00. Where do you purchase this meat thermometer fo $15.00?

I get mine from Lowes. They frequently have them for $15.00 on clearance. I think they are normally $19.00 in the store.

If your smoking at 225 and a dozen gnat's fart....what would the temp jump be??? :)

I see them for around $14.99 -$15.99 at most grocery stores in the "kitchen stuff" area. Also, last time I was in FTW, TX, I picked up another one at "Barbques Galore", just off of S 820 by Mimi's Cafe.

The model #'s I have (both) #00648.

Also, Google "acurite bbq thermometors". Saw them for $16.99 to about $27.99 at several places.

Well I work on computers for a living. I go home and somebody's always got a computer problem for me to fix. I have a photography business on the side, which requires computers. So, yea, sometimes a guy has to unplug....I never lasts long though ;->

While I was joking (sorta') about the gnat fart, I do want to know when the temperature changes even the slightest amount. When using PID loops to control temperatures, you have to keep in mind the concept that there is a delay between an intake adjustment and the actual change in temperature. If you round off to the nearest 5 degrees or so (which is the same result you get from probes that are not sensative enough), your temperatures will bounce; like in a "bang-bang" type thermostat in an electric oven. In the grand scheme of things, I suppose it's not a big deal, they say: those that

Geek, I know it was sort of a joke, but it was funny and I had to add my .02 in....but thinking about gnat's they come mighty big down here near the water (except for the no'seems, which have a nasty byte).

Great! So what you are telling me is, I now need to add a conversion factor in my program to account for Inter-State Gnat farts. Man....this is getting complicated icon_biggrin.gif
