EVM-7 Multiparameter Environmental Monitor
The EVM-7 is a rugged, easy-to-use environmental monitor that combines particulate monitoring, air quality monitoring, and gas detection into a single device. It can simultaneously measure and log mass concentration particulates, volatile organic compounds, toxic gas, and carbon dioxide. Its large display and buttons, simple screens, straightforward commands and robust software solutions put all of the EVM-7’s capabilities right at your fingertips. It features a dial-in rotary impactor system for quick particulate selection (PM2,5. PM4, PM10, or TSP).
With the addition of an optional AirProbe kit, the Quest EVM-7 can also monitor relative humidity, temperature, and air velocity.
EVM-7 Series models available with additional CO and/or PID (ppb) sensors.
EVM-3 Environmental Particulate Monitor
The EVM-3 is a tri-sensor instrument that measures particulates, temperature and relative humidity. The EVM-3 uses a built-in sampling pump and dial-in impactors to collect mass concentrations of particulates and the laser photometer captures real-time measurements.
EVM-4 Multiparameter Indoor Air Quality Monitor
The EVM-4 Series has the ability to simultaneously monitor and log carbon dioxide, relative humidity and temperature and one toxic gas. The device has the capability to measure one of nine different user-selectable toxic gases.
This multi-sensor instrument designed for indoor air quality investigations: It lets you simultaneously track, log and monitor multiple indoor air quality parameters, including room air exchange rates and dew point.
EVM-4/CO model available with additional CO sensor.
