Supplied with 3.1 and calibration certificates
Type B mineral insulated thermocouple cable
Type B mineral insulated thermocouple cable is designed for very high-temperature measurement, with an approximate temperature range from 600°C to 1700°C. Type B provides particularly stable and accurate readings above 1000°C, making it suitable for demanding high-temperature applications in furnaces, glass, steel and ceramics.

When should you use Type B MI thermocouple cable?
Type B thermocouples stand out for their resistance to degradation and drift, particularly at extremely high temperatures, compared to other noble metal thermocouples like Types R and S. Their resilience makes them a preferred choice in industries that operate at very high temperatures, such as the furnace industry for temperature monitoring and control, as well as in the glass, steel, and ceramics industries where precise and reliable temperature measurements are essential.

Type B is also available in thermocouple bare wire.
