Thermocouple Wire
Fine Diameter Base Metal
In order to meet the immediate needs of science and industry for highest quality
thermocouple wire in practical quantities at reasonable prices, OMEGA makes available
thermocouple materials in a variety of wire sizes. The wire is supplied uninsulated on
standard 76 mm (3") diameter plastic spools in continuous 15 m (50') lengths.
Sizes range from 0.013 to 3.25 mm (0.0005 to 0.128") diameter. The wire is supplied
as single legs or in matched pairs to meet standard limits of error. Other wire sizes and
quantities are available on special request.

of Constantan. Each
form is composed of
the same elements, but
the percentages (%) of
constituent elements differ.
One is matched to Iron.
The other can be matched
to Copper or CHROMEGA®.
When ordering matched
pairs, be sure to specify
SPCI with SPIR and SPCC
with SPCP or SPCH.
