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 max- imum 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 can be specified by doubling the type letter in the part number. Example: 24KKP
