Industrial PM2.5 Sensor

The dual channel PM2.5 sensor measures fine particle concentrations for an effective air quality improvement strategy.

This dual channel PM2.5 sensing system measures fine particles in two air channels simultaneously, for instance when used in a building HVAC (heating, ventilation and air-conditioning) system. Based on the particle measurements, the filtering and recirculation control can be optimized to improve the air quality of the interior. Moreover, the difference between outside and inside air quality can be visualized on a display.

Accurate measurements to improve air quality
The system's precise measurements allow a real-time comparison of the level of fine particles in the exterior and interior air. This information is used to implement a strategy to control the HVAC system and improve the air quality inside, for instance in a building. The performance of the air filtering system, as well as the interior and exterior air quality can be shown on a display.

Air pollution is a serious threat to human health. PM2.5, also known as fine particles, can cause various health issues and is known to decrease life expectancy. The PM2.5 concentration in the air is therefore an important indicator of air quality and measuring fine particles provides insight to improve air quality.
