What is Platinum Rhodium thermocouple temperature sensor?
Platinum Rhodium thermocouple temperature sensor is a traditional temperature measuring element, which has stable thermoelectric performance and strong oxidation resistance, and is suitable for continuous working in oxidizing and inert atmosphere. The long-term working temperature is 1600℃, and the short-term working temperature is 1800℃.
