mbw SF6 decomposition device for gas measurement

Measurement of Water Vapor To ensure that corrosive electrolytes remain at low concentration levels, it is important to make periodic measurements of the water vapor content of the gas used within the SF6 filled equipment. Chilled mirror technology is commonly used as an accurate, reliable, and robust method for measurement of water vapor in SF6. While the initial cost to obtain the chilled mirror equipment is somewhat higher than systems
