This type of thermocouple is a low cost and most used thermocouple. Available in 8 ga., 14 ga. and 20 ga. with standard calibration tolerances. TYPE J THERMOCOUPLE (Iron/Constantan) Composed of a positive leg which is iron and a negative leg which is approximately 45 % nickel-55% copper. Show. It may also be necessary to check a thermocouple that will be used for a measurement standard. Wire core material: Type K: NiCr - NiSi; Type T: Copper - CuNi; Type J: Fe - CuNi. When protected by compacted mineral insulation and appropriate outer sheath, Type J is useable from 0 … The most common types of temperature thermocouples are type j thermocouples and type k thermocouples. Set Descending Direction. FREE Shipping on orders over $25 shipped by Amazon. Type JX extension wire is suitable from 32° to 392°F. Type J Thermocouple . Reference ANSI MC96.1-1982 for special grade thermocouples. Get it as soon as Fri, Jan 8. (Note - Constantan is Copper-Nickel.) Type S Thermocouple. Also, some materials are strongly to slightly magnetic: Type J Positive (strongly Magnetic), Type K Positive (slightly magnetic). 1 product rating - TEMPCO TTW00178 THERMOCOUPLE PROBE TYPE J LENGTH 3' $22.99. The procedure to read the type T thermocouple table is exactly the same as the one from the type K thermocouple table. Categories. The positive lead is made of iron and a negative lead is made of constantan (45% nickel and 55% copper). Type R Thermocouple. 3/16" Diameter 12" Bendable Probe Thermocouple Type K. $52.06.
