Bare Thermocouple Wire is supplied as a PAIR with both the positive and negative non-insulated wire for the thermocouple type listed.  These are non-terminated on each end (no weld or "Hot Junction").  However, Accu-Glass Products does offer this service.  

 

  All thermocouple wire in the list below is match Thermcouple wire and is NOT EXTENSION GRADE WIRE, therefore it is sold in short 1 foot or 1 inch lengths.  This thermocouple wire CAN be used with our "standard" subminiature-D feedthroughs.   Most applications will not register the small amount of error introduced by using non-thermcouple alloy pins in the feedthroughs.  The error that is introduced is below acceptable limits for thermcouples and can be taken into account during calibration.
