J Type Thermocouple, Temperature Range: 0 to 750 deg C, 0 - 150 mm

Being an eminent organization in the industry, we are involved in providing a premium quality range of Wire Type Thermocouple.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. Type J has sensitivity of approx 50 microvolts/ degree C .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.
