Probes are designed for use in
extreme temperatures, up to 2315°C
(4200°F). These probes utilize either
Platinum/Rhodium (types R, S, or
B) or Tungsten/Rhenium (types G,
C, or D) elements, with a variety of
insulations and sheath materials.
Depending upon the sheath material
selected, these probes may be
used in inert, oxidizing, reducing or
vacuum conditions. The maximum
temperature is based on the lowest
maximum temperature of the element,
insulation and sheath material.
Five cold end probe terminations
are available: replacement probe,
subminiature or standard size ceramic
connector, heavy-duty standard
size, molybdenum-sheathed nylon
connector, or transition joint with
2 m (72") lead wire.
† Non-metallic sheaths are also available.
