The MVI: A Portable Mercury Vapor Indicator

Unlike conventional gold film detection methods, the dual beam UV absorption technology of the portable mercury vapor detector does not saturate or need regeneration between readings — thereby minimizing wasteful instrument downtime.

Thanks to its fast-acting precision, the portable mercury vapor indicator offers a real-time response and is ready for instant detection. MVI provides continuous readings and has been fitted with two detection ranges: 0.1 to 199 and 1 to 1999 µg/m3.


The portable Mercury Vapor Indicator's pump makes use of high-performance technology for quick indication and recovery. The large digital display on the instrument and audible alarm show the levels of mercury present.

This instrument has been ergonomically developed for simple, one-handed operation. MVI is the optimal survey unit for quick and accurate mercury detection.
