Nutech Engineers manufactures Magnesium Oxide [MgO] Insulated Thermocouples. Nutech Engineers is an ISO 9001:2000 awarded company. The Magnesium Oxide [MgO] Insulated Thermocouples are recommended where the thermocouple is immersed in liquids, high moisture, corrosive gases, or high pressures. The thermocouples can be formed to reach otherwise in-accessible areas. The magnesium oxide has a high dielectric strength, responds quickly to temperature changes, and is very durable. Magnesium oxide insulated thermocouple wire is manufactured from premium quality wire in cased in pure magnesium oxide and processed into a chemically clean outer metal sheath. The wires are individually selected and matched and are of uniform cross section with smooth surfaces.
