pm2.5 monitoring

AntrumX™ centralizes sensors in our patented sensor pack, allowing multiple indoor air quality (IAQ) parameters to be measured simultaneously from an easily accessible location. AntrumX continuously draws air samples from each monitored space to the sensor pack located in the control panel, where it measures and reports data to the building management system and the cloud for further analysis.

Particulate matter (PM) is the term representing the sum of all solid and liquid particles suspended in air, many of which are hazardous. Exposure to these dangerous microscopic solids and liquids can adversely affect human health, with fine particles (PM2.5) being the most dangerous.

Supplying adequate outdoor air and maintaining appropriate ventilation are critical to reducing exposure to harmful particulate matter inside commercial buildings. Optimized ventilation dilutes airborne concentrations of indoor contaminants, improving indoor air quality, occupant comfort and efficiency, and ensuring an overall healthier building.

The PM sensor in the AntrumX sensor pack bins at PM1.0, PM2.5, PM4.0, and PM10.0 microns using a proprietary contamination-resistance technology coupled with optical sensors that utilize a laser-based scattering principle. This innovative technology enables long-lasting, highly accurate measurements. The sensor is also equipped with advanced algorithms, providing superior precision for different PM types and advanced particle-size binning through calibrated digital output.

AntrumX’s centralized IAQ monitoring technology guarantees more accurate, consistent, and cost-effective IAQ data, leading to a healthier and more efficient building.
