Air Quality Monitor Measures Dust and VOCs

The EVM from Shawcity (UK) is a rugged and easy to use environmental monitor which combines several instruments in one. With the capability to simultaneously measure and datalog particulates, Volatile Organic Compounds (VOCs), toxic gas, carbon dioxide, relative humidity, temperature and air velocity the EVM-7 provides a cost effective solution and reduces the need for multiple instruments. This versatility enables it to be used in the industrial, commercial and education sectors.

A unique dial-in impactor allows easy selection of particulate settings. A built-in sampling pump assists in the collection of dust and a photometer provides real-time measurement. A standard 37 mm filter cassette offers gravimetric sampling and laboratory analysis.

Using a high-performance PhotoIonisation Detector (PID) EVM-7 measures volatile organic compounds (VOCs). Combined with the ability to also simultaneously measure carbon dioxide and another toxic gas, it helps to identify air quality issues. Additionally, EVM-7 uses smart sensor technology, which offers automatic sensor recognition at power-on, calibration levels, service dates, temperature compensation and other sensor specific data.

Sampling sessions and studies stored in the internal memory can later be downloaded into datalogging software for analysis, charting and graphing.
