LUMEX online air mercury analyzer RA-915AM

The RA915-AM is used for real-time monitoring of mercury content in the atmosphere, and can automatically and continuously measure mercury content in the atmosphere and indoor air. The system can operate unattended and can be installed on a 19 inch rack in the monitoring room. Meets the EU air mercury monitoring standard EN 15852. Participate in the GMOS mercury monitoring system project, monitor atmospheric mercury content and its forms through land, ship, and aerial observation methods, study long-term observation data of mercury in the atmosphere in background areas such as Europe, Africa, and polar regions, and investigate the regional and range transmission and deposition of mercury in the atmosphere.

Working principle of LUMEX online air mercury analyzer RA-915A AMThe RA915-AM analyzer uses the principle of high-frequency modulated polarized light Zeeman atomic absorption spectroscopy (ZAAS-HFM) to analyze the absorption of 254nm resonant emission lines by mercury vapor.

Application area: RA-915A adopts high-tech environmental atmospheric background monitoring, suitable for online monitoring of environment, indoor atmosphere, industrial waste gas, etc
