OMEGA's fine gage single strand thermocouple wire is available in 50, 100, 500 and 1000 ft. spools. Each spool represents a single leg of the thermocouple. Wire diameters range from 0.07mm(0.003") up to 0.81mm(0.032"). The wire is covered by extruded PFA insulation. The insulation thickness is 3 mil for wire sizes equal to and less than 0.25 mm (0.010"). For wire sizes greater than 0.25 mm (0.010"), the insulation thickness is 8 mil.

Rated 5 out of 5 by from Easy to work with We required the finest gauge thermocouple wire possible for our application and found that this gauge, with the insulation was a perfect balance between strength and small size. One gauge size lower and the wires were constantly breaking.

What is the accuracy of this thermocouple wire?

Asked by: racks_on27
The accuracy of each type of wire pair is based on the ANSI MC 96.1 specification and can be found by doing an on line search or requesting a copy by contacting the Omega Temperature group.

What does the temperature range mean? Is it the temperature that the wire can measure or the temperature at which the wire will melt?

Asked by: Anonymous
Thank you for your inquiry. The temperature range is what this wire can measure and if you use this wire to measure temperatures above 260 C, the wire will melt.
