Mineral Insulated Thermocouples, commonly referred to as MgO (Magnesium Oxide) thermocouples, are used in many processes and laboratory applications. They are available in all thermocouple element types and a wide variety of sheath diameters and materials. They are rugged in nature and bendable, and their fairly high-temperature ratings make MI thermocouples a popular choice for a multitude of temperature measuring applications.
