SF Maintenance Equipment Fundamentals

Moisture levels must be kept to a minimum to reduce the formation of acidic by-products, such as HF, SO 2, SOF 2, etc. Hygrometers, or moisture-measuring devices, built to work in the corrosive environment of arced SF 6, will quantify the level of moisture vapor in gas. Because the amount of moisture present in the vapor state will fluctuateGet price
