These probes utilize either Platinum/ Rhodium (Type R, S, or B) or Tungsten/Rhenium (Type C or D) elements and a variety of insulations/ sheath material. Depending on the sheath material selected, probes can be used in inert, oxidizing, reducing or vacuum conditions. The maximum temperature of the final assembly is based on the lowest maximum temperature of the element, insulation and sheath material. **High Temperature Standard Connector - Style Q** we nt **Transition Joint - Style TJ-BX Miniature Connector- Style MQ** ee’Ce **Cast Iron Protection Head- Style NB1/NB12** Cold end probe terminations are available in: replacement probe (RP), standard or subminiature ceramic connector, standard or subminiature heavy-duty nylon connector, or transition joint with 2 m (72”) braided fiberglass lead wire. Other options available on page 3/4 , or contact sales. For types R and S, wire accuracy meets special limits of error (SLE); on all other thermocouple types, wire accuracy meets standard limits of error. ## Part number Breakdown / Example **XMO - W5R26 - U - 125 - 30 - A - Q - 12 - Dual** i **1 2 3 4** Paes **5 6 7 8 9** - All probes are ungrounded. - Dual Configurations available. Allows two reads from a single point. Consult page ( WITH APPROPRIATE ORDERING CHART) for all options. - Specify Termination Style: Q, HX, MQ, SX, TJ, TJ-BX, TJ-SB, RP, NB, NB-LK. *Cold En d Termination temperature ratings found on page 3. - Specify Probe Length in Inches (1” = 24.5mm). - Refractory metals are extremely sensitive to any trace of oxygen above approximately 260°C (500°F). Must be used in vacuum or in very pure inert gases such as Helium or Argon. - For Type C and D, ANSI color codes are used, as there is no IEC standard. - Images throughout spec sheet are for reference only. - Non-Metallic sheaths are available.
