NextPM Advanced

Reliable particulate matter (PM) monitoring in demanding environments.

PM

Designed specifically for air quality measurement in ventilation ducts and HVAC systems, the NextPM Advanced replaces the internal fan with an end piece that connects to an external pump. This design ensures stable operation under significant pressure differences, delivering reliable particulate matter (PM) monitoring in demanding HVAC environments. The sensor provides real-time PM1, PM2.5, PM10 and TSP1 data in both µg/m³ and pcs/L.

Key Features

  • External pump
  • Extended operational range
  • Real time PM1, PM2.5 and PM10 + TSP
  • 5 channel in pcs/L
  • Airflow 1 L/min
  • Lifetime >10,000 hours
  • Communication UART / Modbus (RS485)
  • Pressure loss compliant
