Description Features & Benefits

EVM Environmental Monitors

The EVM-7 measures both particulates and air quality, and provides a lower cost of ownership by combining three instruments into one. Additional models include the EVM-3, specializing in direct reading of particulate mass concentrations, and the EVM-4, designed for indoor air quality studies.
