Mercury Vapor Monitor for continuous measurements in air and other gases


Perfectly adapted for continuous Air Quality monitoring, laboratories, environmental surveillance, quality control, etc.

The VM-3000 Mercury Vapor Monitor measures continuously the Hg concentration in air and other gases. It is used for laboratory applications as well as installed at places where mercury has to be monitored. It is a great tool for many different fields of applications in scientific research or the industrial sector
