Hi Craig- If you look at the Labjack forum, there is some discussion about this. Using an Edelbrock TK-4 thermocouple converter will work provided you give it a negative supply. This will allow up to 16 thermocouples to be connected to a Labjack U3. Or- you could build your own thermocouple amplifie...

You can get these current transformers: http://rocky.digikey.com/WebLib/Amveco-Talema/Web%20Data/AC1025.pdf for about six bucks each from Digi-Key. Put a 100 ohm resistor across each one and bring the pins out to a couple of tip jacks on a panel, and you're done. I would think that as small as these...

Hi Craig-
As for the hardware, how about this: http://www.labjack.com/labjack_u3.php?prodId=25
You'll probably need to add some external gain and cold-junction compensation externally to get the thermocouple outputs up to a reasonable level that the LabJack can handle.

TJ Byers passing
I was stunned to find a small block at the bottom of page 6 of the February issue about the death of TJ Byers on January 11th. I have enjoyed reading his columns for several years and have learned quite a lot from him. It's a bit eerie that in the same issue that announced his death there is a curre...
