Fixed Air Quality Station (AQ-200)

Air Quality stations deliver precise measurement data in real-time for a wide range of air pollutants in a discreet and compact package. Measurable parameters include: ozone (O3); nitrogen dioxide (NO2); nitrogen oxides (NOx): carbon monoxide (CO); carbon dioxide (CO2); sulphur dioxide (SO2); volatile organic compounds (VOC); and particulate matter by mass (PM10 and PM2.5) or size distribution (0.3 to 10 µm, 8-channels)

  • Multiple gas measurements
  • Real-time data acquisition
  • Multipoint factory calibration
  • Zero and Span calibration user facility
  • PC software included
  • Temperature and humidity sensors
  • Remote site operation
  • Particle monitoring PM2.5 PM10, TSP*
  • Pole or wall installation
  • Wind speed and direction sensors*
  • Compact and low weight

AQ-150 is suitable for monitoring particulate emissions from cyclones, precipitators, baghouses, or any dust control device. It is also ideal for monitoring air quality in underground transportation systems, ventilation systems, indoor workplaces, or any other application where immediate data on smoke, dust, fumes, or mists is needed. AQ-150 warns you of problems before they become trouble.

AQ-150 utilizes an optical layout consisting of an infrared emitter and silicon detector. As particles enter the sensing area an analog output, current or voltage, provides a signal which is proportional to the particle concentration. The signal can be sent to a recorder or central processing panel.

AQ-150 easily mounts on walls, inside air ducts or at strategic locations in dust collectors, bag houses, or any dust control device. Units can be configured in a single or multipoint system.
