HS-EMQA Air Quality Monitoring Station (PM2.5, PM10, CO, SO2, NO2, O3, TVOC, Temperature, Humidity)

Reference: HS-EMQA
Brand: HenSistemas

HS-EMQA is a multi-parameter system for online air quality monitoring. It tracks the main pollutants and conditions: PM2.5, PM10, CO, SO2, NO2, O3, TVOC, temperature, humidity, etc.

Typical uses include industrial production sites, tunnel traffic and urban environments. By collecting and analyzing atmospheric data, it improves how air pollution data is processed and managed, and it gives environmental planning and assessment a basis for decisions.
