TSI Quest EVM-7 Series Multiparameter Environmental Monitors

The TSI Quest 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.

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.
