J Type Thermocouple Wire

Product Details:

Type J thermocouple is a very common and general purpose thermocouple. It has smaller temperature range and a shorter lifespan at higher temperatures. It consist of positive leg  made of an Iron wire and negative leg made of an Constantan ( Copper-Nickel ) alloy wire. Due to the Curie Point of the iron at 770 °C Type J has a limited temperature range of 0°C  to 750°C.It should not be used at high temperatures in an oxidizing atmosphere as iron undergoes a molecular change and permanently loses its standard voltage output versus temperature. It does not recover when the iron is cooled. The expenses and reliability of Type J is same as Type K. For proper working of J Type thermocouple reduction atmosphere is desired and use at low temperature  is also not recommended.

If the Client need the customized Sensor size. We can customize the product in the minimal time delay.
