Ion Science MVI — Portable Mercury Vapor Indicator / Mercury Vapour Analyzer
The Ion Science MVI is a portable mercury vapor indicator that delivers immediate, real-time mercury readings in the field. You do not need to know where the mercury is before you start — a high-performance pump and PTFE probe let you sweep an area and let the instrument find the contamination.
Two things separate it from spot-checking instruments. It gives continuous readings rather than discrete samples, and it needs no regeneration between readings, so there is no waiting period before the next measurement. Detection is by dual-beam ultraviolet absorption, with a response of roughly three seconds.
Probes and consumables
PTFE probes, water trap filters, the MVI data logger, battery chargers and power supplies are stocked in MVI Spares & Accessories. The water trap filter is a routine consumable — keep spares on hand for field work.

- Finds mercury, does not just confirm it — sweep an area with the probe rather than needing to know the location in advance
- Continuous real-time readings — not a spot checker, so concentration can be tracked as you move
- No regeneration between readings — no enforced waiting period before the next measurement
- Roughly three-second response — fast enough to trace a concentration gradient back to its source
- Accurate to ±10% of reading or ±5 micrograms — well ahead of instruments quoting ±20%
- One-handed operation — large digital display, audible alarm and a PTFE probe with moisture trap filter
- Contaminated land investigation — locating and delineating mercury contamination across a site
- Environmental site assessment — due diligence surveys of former industrial and manufacturing property
- Industrial hygiene — workplace exposure surveys in chlor-alkali, dental, laboratory and instrument-making settings
- Spill and breakage response — confirming the extent of contamination and verifying cleanup
- Decommissioning and demolition — surveying plant and buildings before work begins
- Waste handling facilities — screening incoming material and monitoring processing areas
