In addition to the J thermocouples listed above, we also supply the K type thermocouples. K thermocouples are normally used in the
temperature range of -200°C to 1250°C.
I
ron-constantan thermocouples
are low cost devices used to
measure temperatures to 800°C.
These iron-constantan thermocouples
are often referred to as J thermocouples
and are the standard thermocouples
used in gas chromatographs, mass
spectrometers, and other laboratory and
industrial equipment. The smaller the
diameter of the thermocouple wires, the faster the response time but the more limited the
temperature range and structural strength of the thermocouple. All thermocouples are
supplied with 12” leads. Two styles are available: bare wire thermocouples and ceramic
insulated thermocouples. The bare wire style contains no insulation of any kind on the bare
thermocouple wires. The insulated style contains a 2 hole by 6" length of ceramic insulat-
ing tube. This insulates the thermocouple leads and prevents their shorting out. If desired,
the ceramic tubes can be cut or broken to shorter lengths.
In addition to the iron-constantan thermocouples, S.I.S.
™
can supply other types and
configurations of thermocouples. Call or write with your requirements.
