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 Thermocouple 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-thermocouple alloy pins in the feedthroughs. The error that is introduced is below acceptable limits for thermocouples and can be taken into account during calibration.
