For these reasons, a few spare TCs should always be kept on hand. Regular calibration or replacement is required to ensure accurate and reliable measurements. TCs will drift over time and become less accurate before failing. Type C TCs have the highest available range and when sheathed they can be employed in vacuum, inert, reducing or oxidizing environments. MRF High Temperature Furnaces typically use Type C sheathed thermocouples for measurements up to 2000☌, beyond that an optical pyrometer is added to supplement the measurement range. Thermocouples are a popular means for measuring temperature due to their simplicity, relative low cost, and availability of different TC types for different environments and temperature ranges. Vacuum, Inert, Oxidizing or Reducing Environments.Mesh heaters, Panel Heaters, Rod Heaters.MRF manufactures hot zones with the following metals: Our high-quality workmanship, the excellent performance of our zones and our competitive pricing make using MRF made parts an easy choice.
