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

We are a unique entity in the industry, actively committed towards manufacturing an optimum quality range of J 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 -40°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.Features: Highly stable Easy installation Sturdiness
