Ion Science MVI Portable Mercury Vapor Indicator

The Ion Science MVI is a portable mercury vapor indicator that delivers immediate, real-time mercury vapour readings in the field — no sample collection, no lab turnaround, no waiting days for a result before you can make a decision. Its dual-beam UV absorption detection avoids the saturation and lengthy regeneration cycles that hobble gold-film mercury analyzers, so the MVI recovers quickly after high-concentration exposure and keeps surveying. Supplied in a premium carry case, it is built for survey work where you need to map mercury distribution across a site or building in a single visit.

APPLICATIONS

Contaminated Land Investigation: Former chlor-alkali plants, gas works, mining, and smelter sites.

Industrial Hygiene Surveys: Worker exposure screening in mercury-handling facilities and laboratories.

Spill Response and Clean-Up Verification: Locating residual mercury and confirming remediation endpoints.

Building and Property Surveys: Schools, hospitals, and labs with historic mercury use; pre-demolition assessment.

Oil, Gas, and Utilities: Mercury screening in natural gas processing, meter shops, and pipeline maintenance.

Waste Handling and Recycling: Lamp, battery, and switch processing facilities.

WHY THE MVI

• Real-time readings — survey and decide on site rather than waiting on laboratory results

• Dual-beam UV absorption: no gold-film saturation, fast recovery from high exposure

• Portable and survey-oriented, supplied in a premium carry case

• Optional data logger for recorded, reportable survey datasets

• PTFE water trap filters protect the optical bench in humid and dusty conditions
