How to choose a high-temperature thermometer
Thread Content
The laboratory needs to conduct reactions at high temperatures of 1100°, and there are corrosive gases present; what type and material of thermometer would be suitable?
A thermocouple will do. The material is high-temperature and corrosion-resistant ceramic.
Reply to 2# Romantic Nohtaka: Thermocouples for measurement (scale rating R or S0-1300 degrees / scale rating B0-1600 degrees). High-alumina porcelain tubes used for protective sleeves can be used at 1500 degrees, with a maximum of 1600 degrees.
Division number S, platinum-rhodium-platinum thermocouple, measurement range 0 – 1600°C. Corundum (cerametal) is used for the sleeve.
