TSI Quest EVM Environmental Monitors range formerly by 3M, provide a combined solution for the monitoring of particles, gas concentrations, volatile organic compounds, relative humidity, temperature and air velocity. Separate analysers are no longer needed reducing the equipment burden.
Operation is menu driven, using ten push buttons and four soft keys. Options are displayed on a back lit LCD 128 x 64 display.
An integrated light scattering photometer with built in sample pump provides real time particulate measurement 0.1-10 μm. Dial in technology allows four particle sizes to be chosen without switching external cyclones. PM2.5, PM4, PM10, and PM. (PM is unfiltered particulate all sizes). Data logging is included, logging intervals in seconds 1, 5, 15, 30, minutes 1, 5, 10, 15, 30, 60. The data can be used with Detection Management Software compatible with other instruments to create a common platform. Retrieve data, create reports and charts, configure the EVM environmental monitor.
There are three models in this this range
EVM-3 Particulate Monitor only, measuring particles, temperature, relative humidity and air velocity optionally be can be added.
EVM-4 Indoor Air Quality only, no particulates, measures temperature, relative humidity, air velocity (extra) and Carbon Dioxide, plus one toxic gas sensor.
EVM-7 Has all the functionality of both models combined above, but also measures in addition volatile organic compounds.
The toxic sensor addition for the EVM-4 and EVM-7 models is a choice of the following: Carbon Monoxide, Chlorine, Ethylene Oxide, Hydrogen Cyanide, Hydrogen Sulfide, Nitric Oxide, Nitrogen Dioxide, Oxygen and Sulfur Dioxide.
