Noble Metal Thermocouples

Noble Metal Thermocouples are manufactured with precious or noble metals like Platinum and Rhodium. Noble metal thermocouples can be used in oxidizing or inert applications and must be used with a ceramic protection tube surrounding the thermocouple element. These are normally used for high-temperature applications. These sensors are usually fragile and must not be used in applications that are reducing or in applications that contain metallic vapors.
