The MR-A ambient air quality monitor is a portable instrument designed for comprehensive environmental air quality monitoring. Compliant with Class C methods of air and exhaust gas analysis, as promulgated by the State Environmental Protection Administration, this monitor simultaneously measures at least four key gas and particulate matter concentrations.
It monitors ambient gases including SO2, NO2, CO, O3, and particulate matter concentrations like PM2.5 and PM10. Expandable capabilities allow for monitoring over thirty additional gases such as VOC, H2S, NOX, CH4, HCl, HF, Cl2, NH3, CO2, and dust particles (TSP). It can also measure meteorological parameters such as temperature, humidity, atmospheric pressure, wind speed, wind direction, illumination, ultraviolet radiation, solar radiation, noise, and negative oxygen ions. Utilizing its core algorithm, the MR-A achieves high-precision detection with a resolution of 1ppb.
Suitable for environmental monitoring agencies, industrial facilities, construction sites, and research institutions requiring accurate and reliable air quality data.
