Metal sheath or mineral insulated (MI) style thermocouples are used in applications that require resistance to the harsh environment and temperatures for consistent readings.
All of our magnesium oxide insulated thermocouples, commonly referred to as MgO thermocouples, meet the special limits of error tolerances of ASTM E230 Tale 1.
We stock multiple diameters, sheath materials, and calibration types to meet your specific needs.
