MVI mercury vapour detector

Accurately detects mercury in just 3 seconds!

The Mercury Vapour Indicator (MVI) is a revolutionary mercury detector, detecting mercury vapours in just 3 seconds!

The instrument’s dual beam UV absorption technology means MVI does not saturate or need regenerating between readings – like traditional gold film detection methods – eliminating instrument downtime.

Fast and accurate, the MVI mercury detector gives a real-time response and is ready to detect instantly. MVI provides continuous readings and offers two detection ranges: 0.1 to 200 and 1.0 to 1999 microgram/cubic meter.

MVI is a portable mercury vapour detector that utilises a high-performance pump for fast indication and recovery. The instrument’s audible alarm and large digital display clearly indicate the levels of mercury present.

Ergonomically designed with simple, one-handed operation MVI mercury vapour detector is the ideal survey unit for rapid and accurate mercury detection.
