TSI Quest EVM Particulate and Air Quality Monitor
The TSI Quest EVM Particulate and Air Quality Monitors can simultaneously measure particulates and gas concentrations in real-time. There are 7 options available for this monitor with temperature, relative humidity, particulate, CO, CO2, and PID measuring capabilities. It provides a lower cost of ownership, combining three instruments into one. This also makes it easily transportable thanks to its compact and lightweight design.
The TSI Quest EVM can measure particulate mass concentrations (0.1-10 μm), select toxic gases, select VOCs, Carbon dioxide, relative humidity, temperature and air velocity. It has a built-in sampling pump that allows simple capturing of particulate samples. Also with a 90° light-scattering laser photometer, which enables real-time particle measurements.
After data has been logged and you have stopped your measuring session, data can be viewed in the past session summary menu. Additionally, TSI Detection Management software makes sure analysing time history data is simple and efficient.
