EVM Series

The EVM is designed for comprehensive indoor air quality analysis with its ability to simultaneously monitor and log one toxic gas, carbon dioxide, relative humidity and temperature. Multi-sensor instrument designed for indoor air quality investigations. Simultaneously tracks, logs and monitors multiple indoor air quality parameters, including room air exchange rates and dew point. The EVM7 also monitors particulate and aerosol in the air. VOC vapors are also detected by the EVM7.
