Portable mercury analyzers that use advanced Zeeman Background Correction technology to provide direct measurement of mercury vapor in air and gas streams without sample preparation. These instruments are widely used for environmental monitoring, emergency response, industrial hygiene, and rapid field screening of mercury contamination.
Both analyzers provide direct, real-time mercury vapor measurements in air using advanced Zeeman Background Correction technology. The Light-915M2 is designed specifically for portable mercury vapor monitoring in ambient air, while the RA-915M is a multi-function platform that can be expanded with attachments to analyze mercury in air, gases, liquids, solids, and sorbent traps.
