SF Maintenance Equipment Fundamentals

Moisture 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 willGet price

Moisture meter - Wikipedia

A moisture meter gives a reading of the approximate moisture content of wood. The reading helps in determining whether the wood is suitably dry for its intended purpose. The moisture content reading can also assist in planning a project design that will accommodate future changes in dimension caused by changes in relative humidity.Get price

How to Interpret Moisture Meter Readings on Different Scales

In many cases, a moisture meter’s reference scale will range from 0-100, but that reading should not be confused with a percentage. Some meters use a 0-300 reference scale, so readings taken on a reference scale often do not correlate with one another. Some ways to use a moisture meter with a reference scale include: Quick Pass/Fail MoistureGet price
