When selecting bare thermocouple wire, keep in mind that a larger gauge wire will give a longer service life, slower temperature response time, and a higher maximum temperature limit. A smaller gauge wire, which will give you a lower maximum temperature limit and a shorter service life, will have a faster temperature response time.

Standard limits of error are provided as specified below. Special limits can be specified by doubling the type letter in the part number.
