Quest EVM 7 CO-CO2-Advanced ParticulateAir Quality Monitor

Pine Item #
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.

Particulate, gas and photoionization detector (PID) measurement from a single device

Less equipment to carry to job site; compact, user-friendly design

90-degree light scattering laser photometer measures particulates in real-time

Proprietary technology for selecting particulate settings; no need for external cyclones

Built in sampling pump allows for gravimetric analysis

Large, easy-to-read display with trend graphing for measurements

Time history data logging and compatibility with Detection Management Software makes analysis efficient
