ION Science MVI Mercury Vapour Indicator

Mercury Vapor Detector

Ion Science’s MVI (Mercury Vapor Indicator) is a portable mercury detector which can accurately detect mercury vapor in just three seconds, with detection ranges of 0.1–200 and 1–1999 micrograms/cubic meter. It does not saturate and does not need to regenerate, allowing for more detection uptime. The MVI is ready to detect within minutes and is capable of continue operation for 5½ hours.

The Mercury Vapor Indicator (MVI) is capable of accurate detection of mercury vapors in three seconds. The MVI features dual-beam UV absorption technology and ability to measure high concentrations of mercury without saturating; with no regeneration required between readings.

The MVI is fast and accurate, and ready for detection within minutes. MVI provides continuous readings with two detection ranges: 0.1 to 200 and 1.0 to 1999 microgram/cubic meter, and is ideal for time weighted average (TWA) monitoring.

MVI uses a high performance pump for fast indication and recovery. An audible alarm and large digital display clearly indicate the levels of mercury present. The MVI is ergonomically designed for simple, one-handed operation.
