Features: Super Accurate, Super Stable, Super Value For Use with Temperatures Up to 1335 oC (2440 oF) FOR OTF-1200X-RTP-II Excellent Long Term Stability at High Temperature Nickel-Chrome Based Super-alloy Sheathing Provides Excellent High Temperature Performance Detective probe make temperature measure much more precise measurement. Excellent Oxidation, Carburization and Chlorination Resistance Made with materials of Special Limits of Error. Perfect for calibrating MTI tube furnaces using a precision temperature calibrator (matched with male plug; related product below ) Specifications Length: 18" Diameter of sheath: 1/4" diameter Positive Material: Ni-Cr Negative: Ni-Al Highest Temperature: 1200 oC Material: Ni-Al Lowest Temperature: -200 oC 1/4" thermocouple can be inserted into processing tube via flange and calibrating tube furnace temperature under vacuum *(click picture to order the flange) Application Notes If necessary, please check out K type thermocouple extension wire with mini male plug. Using compensating wires is equivalent to stretching them to keep them operating at a constant temperature. The advantages of using compensating cables are saving material costs and solving the problem of constant temperature, etc. There are 2 polarities for K type thermocouple: positive and negative. Please check polarity of K type thermocouple before use. Wrong polarity may cause temperature measuring error. It is also easy to test the polarity of K type thermocouples. The negative wire is MORE magnetic than the positive wire. Just put a magnet up to each wire. One will be more magnetic than the other. Warning Chromel/Alumel is vulnerable to sulfidic corrosion which can result in a thermocouple failure. Apply a thin layer of Zirconia coating will protect the TC from corrosion and thus extend its service life. Re-apply the coating if there is a sign of layer flaking/peeling after the process.
