Portable Mercury Vapor Indicator: MVI

The dual beam UV absorption technology of the portable mercury vapor detector does not saturate or require regeneration between readings – unlike traditional gold film detection methods –  putting an end to wasteful instrument downtime.

Fast-acting precision means that the portable mercury vapor indicator delivers a real-time response and is well-prepared for instant detection. MVI offers continuous readings and is equipped with two detection ranges: 0.1 to 199 and 1 to 1999 microgram/cubic meter.


The pump on the portable Mercury Vapor Indicator uses high-performance technology for rapid indication and recovery. The large digital display on the instrument and audible alarm clearly express the levels of mercury present.

Ergonomically designed for easy, one-handed operation, MVI is the optimal survey unit for fast and precise mercury detection.
