RA-915AMNG Automatic mercury monitor for natural gas RA-915AMNG online mercury monitor is designed for direct continuous mercury determination in natural hydrocarbon gas. RA-915AMNG performs fully automated unattended measurement 24/7 in a gas flow. • Direct continuous measurements. The gas is analyzed «as is» providing better control of the production process • Highest selectivity Differential atomic absorption spectrometry with Zeeman background correction. DESIGN RA-915AMNG monitor is designed for indoor operation or installation in climate-controlled cabinets. The monitor is mounted in a standard 19-inch rack. The embedded PC controls the measurement procedure, data processing, and data transfer via digital or analog protocols. The monitor may be put into an explosion-proof ATEX-certified enclosure. • No pre-concentration on sorbent traps • Low detection limit and wide measurement range • Long-term calibration stability • No chemicals, no carrier and zero gases • Automatic zero drift and span drift correction • Built-in control and preventive maintenance functions • Low running and maintenance cost • Customized configuration • Autorun function in case of
