Acoem Met One OPX 1025 Optical PM Mass Monitor

A New Standard in Continuous Particulate Matter Monitoring

AAVOS International is proud to offer the Acoem Met One OPX 1025, an advanced Optical PM Mass Monitor designed for superior accuracy and reliability. This instrument provides continuous, real-time particulate matter measurements, making it an essential tool for ambient air quality networks and industrial compliance in the Benelux.

The OPX 1025 moves beyond traditional methods by using an advanced optical particle spectrometer with a polychromatic light source. This technology, combined with the proprietary RealPM™ Dynamic Mass Conversion Algorithm, delivers precise mass concentration data by analyzing particle size and count and automatically accounting for environmental factors.

The Smart Solution for Accurate PM Data

The OPX 1025 is engineered for performance and low maintenance, ensuring you get reliable data with a low cost of ownership.

Key Features & Benefits

  • Advanced Optical Spectrometer: Utilises a polychromatic light source with 4,096 raw size bins, consolidated into 100 bins for highly accurate mass conversion.
  • Proprietary RealPM™ Algorithm: A unique size/density algorithm designed for high accuracy across varying environmental conditions.
  • Comprehensive Real-Time Data: Simultaneously measures and reports $PM_1$, $PM_{2.5}$, $PM_4$, $PM_{10}$, and the coarse fraction ($PM_{10-2.5}$).
  • Controlled Sampling System: Ambient air is drawn at a controlled 16.67 LPM flow rate. A built-in Smart Heater conditions the sample (e.g., to 35% RH or lower) for data integrity, even in damp conditions.
  • High Sensitivity: Offers greater sensitivity than traditional continuous PM mass monitors, with a lower detectable limit of $<0.1 \mu g/m^3$.
  • Low Maintenance Design: Features sheath-flow optics protection, which significantly reduces the need for cleaning and field-service intervals, maximising uptime.
  • User-Friendly Operation: A large graphic touchscreen with an intuitive interface and advanced diagnostics simplifies operation and troubleshooting.
  • Advanced Communications: Fully capable of remote operation, with cloud-based data access and options for integrating meteorological and other sensors.
