The EVM range of indoor and outdoor Environmental Monitors
Product Information
Products
The EVM Environmental range of monitors provide you with several measuring functions in one unit!
The EVM range of environmental instruments are rugged and easy-to-use that combine several instruments in one. It can simultaneously measure and data-log particulates, Volatile Organic Compounds, toxic gas, CO2, relative humidity, temperature and air velocity, thus reducing the need for multiple instruments and offers you particulate & air quality monitoring in one portable unit.
The dial-in impactor allows easy selection of particulate settings PM2.5, PM4, PM10 or TSP, without disassembly. A built-in sampling pump helps collect particulates, while a photometer provides real-time measurement. A standard 37mm filter cassette offers gravimetric sampling and lab analysis.
Sampling sessions and studies stored in the internal memory can later be downloaded into QSP II datalogging software for analysis, charting and graphing, adds the company.
The EVM range of instruments
The EVM3 is a real time direct reading particulate monitor with dial in PM2.5, PM4, PM10 and total dust option using proven light scatter technology.
The EVM4 is a comprehensive indoor air quality monitor with dew point, temp, humidity and air velocity measurement with gas and CO2 sensors fitted.
The top of the range EVM 7 has all the above features with added VOC measurement capability with ppm or ppb scaling.
The EVM can be use with the EVM Outdoor kit for outdoor monitoring applications making this instrument a multi purpose based product.
