Thermocouple Wire - Bare

When selecting bare thermocouple wire , keep in mind that a larger gauge wire will give a longer service life and a higher maximum temperature limit. A smaller gauge wire will give you a lower maximum temperature limit and shorter service life, but will have a faster response time. Standard limits of error are provided as specified by the part numbers shown below. Special Limits of error can be specified by doubling the Type letter in the part number. Example: 20KKP Bare thermocouple wire orders will be spooled plus or minus 10% of the total quantity unless otherwise specified by the customer. Bare thermocouple wires can be supplied on spools, coils, or in cut and straightened lengths. ! Note: 24 gauge Platinel II and 11 gauge Nickel vs. Nickel Moly bare wire is also available.
