High chemical resistance is also available in the 150 degrees Celsius and 250 degrees Celsius heat-resistant families of thermocouple extension wires. This device can be operated only for lesser temperature ranges and has a short lifespan when operated at a high range of temperatures. Visit www.reotemp.com for more information about our products and services. Temperature resistance of PTFE sheath: -60℃~+300℃. FREE Shipping on orders over $25 shipped by Amazon. The conductor materials used in Type K thermocouples are more chemically inert than Type T (copper) and Type J (Iron). Thermocouples should be checked whenever there are indications that the output is not accurate. Also, some materials are strongly to slightly magnetic: Type J Positive (strongly Magnetic), Type K Positive (slightly magnetic). Thermocouple Reference Tables Thermocouple mV versus Temperature . It may also be necessary to check a thermocouple that will be used for a measurement standard. It is not susceptible to aging in the 371 to 538°C, (700 to 1000°F) temperature range. The most common types of temperature thermocouples are type j thermocouples and type k thermocouples. Type J can be used in temperatures from -346° to 1400°F. Type K Thermocouple. For example, on a J-type thermocouple, the positive wire is white.
