PMDuct continuously measures particulate matter (PM1, PM2.5, PM10) in ventilation ducts and HVAC systems, delivering both mass concentration (µg/m³) and particle count (pcs/L) with high repeatability and reliability.
Equipped with the NextPM Advanced sensor, PMDuct resists humidity effects, tracks filter performance, detects duct clogging, and integrates easily with building management systems via Modbus RTU for seamless environmental monitoring.
