Michell - Model QMA601 -Process Moisture Analyzer
The QMA601 Process Moisture Analyzer provides highly reliable, fast and accurate measurement of moisture content in a wide variety of carrier gases. It has a lower detection limit of 0.1 ppmV with reliable accuracy at sub-ppm trace moisture levels. Using Michell’s latest developments in Quartz Crystal Microbalance technology the analyzer measures moisture levels effectively even in gases with changing background compositions. It is fully certified for use in hazardous areas. The QMA601 requires only minimal routine maintenance to ensure low cost of ownership. It features an intuitive ‘through the glass’ touch screen interface which is both easy to use and also means that the analyzer can be interrogated and configured without the need for a hot works permit. QMA601 is suitable for use with natural gas containing up to 20% hydrogen with no further modification required.
