OMEGA™ Exotic Thermocouple 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 max. 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 72-inch lead wire.

For temperatures above 1000°C (1800°F), all insulating materials experience a
substantial decrease in resistivity with increasing temperatures.
** Values given are for compacted insulation. For uncompacted hard-fired insulators,
useful temperature range can be 5 to 110°C (100 to 200°F) higher.
Molybdenum sheathed probes are not recommended in applications where they will be
exposed to carbon, including graphite.
For Graphite environments, Consult Omega's Custom Engineering Department for Pricing and Delivery on Tungsten Coated Molybdenum sheathed T hermocouples.
