Thermocouple molded assemblies with transition joints of molded glass-filled nylon provide an economical yet durable thermocouple probe for a variety of sensing applications. The measuring temperature is limited only by thermocouple type and sheath material. Stainless steel sheaths have a maximum temperature of 1650°F (900°C) with Inconel 600 rated to 2100°F (1150°C). The calibration letter code is an integral part of the mold.
Molded Transition Junction N Type calibration have been discontinued. For other Transition Juncation Probes with a N Calibration available, see the Model TJ36-NNIN Or TJC36-NNIN or TJ36-NNXL or please contact our Temperature Engineering department for a viable replacement.
Standard Dimensions
*Specify junction type: E (exposed), G (grounded) or U (ungrounded). Supplied with Stainless Steel transition joints. To order with 310, 316 or 321 SS sheath, change “SS” in model number to “310SS”, “316SS” or “321SS” respectively; no additional charge. Consult Sales for lengths between 2 to 12", or for lengths over 24".
Note: For pricing/availability on Super OMEGACLAD XL probes, contact Sales or use the To Order or Part Number Builder below. Super OMEGACLAD XL probes are available in Type K calibrations only.

Probes less than 48 inches in length are shipped 'straight'. Probes equal to or greater than 48 inches in length are shipped 'coiled'. If a probe that is 48 inches or longer must ship straight, please add "-SST" to the end of the part number, and add $75.00 to the price of the probe. Maximum ship straight length is 96 inches. Additional shipping fees from carrier may also apply for non-standard length packaging.
