Orion Air Quality Monitoring Systems

Orion Air Quality Monitor (AQM Plus)

Orion AQM Plus measures gaseous pollutants, met parameters, and particulates.

Purpose of Air Quality Monitoring:

Make your environment a healthier and safer place by measuring, analyzing, and understanding the data of air pollution with this outdoor air quality monitor.

Applications:

Urban air quality networks, air pollution monitor, industrial emission monitoring, building automation, and air quality research.

Professional air quality monitoring systems provide immediate, on-site data for analysis, compliance, and decision-making. The basic Orion AQM measures four common gaseous pollutants of nitrogen dioxide (NO2), sulphur dioxide (SO2), carbon monoxide (CO) and ozone (O3), in addition to basic meteorological parameters of temperature, humidity, and barometric pressure. The Orion AQM Plus also includes particulate measurement with PM 2.5 and PM 10 sensor.

  • Monitor both air quality and met data with near reference measurement performance
  • All-in-one units sensor modules for easy installation
  • MicroServer-based monitoring also offers individual sensor options
  • Additional meteorological sensors can be integrated such as wind, precipitation, and solar radiation
  • Cost-effective, compact sensor solution

Air quality measurement device integrates with the Weather MicroServer for monitoring via Cloud Server, any Internet Browser, SCADA systems and/or various industrial protocols.

Sensor Measurement & Specification 

AQM measures the most common gaseous pollutants nitrogen dioxide (NO2), sulphur dioxide (SO2), carbon monoxide (CO) and ozone (O3), with near-reference measurement performance. Incorporating temperature, humidity, barometric pressure, algorithms compensate for the impact of ambient conditions on the sensor elements.

With an enclosure made of anodized aluminum and stainless steel, and a protective rating of IP65, the AQM sensors are built to withstand industrial environments.

Many additional sensor options are available with the Weather MicroServer.

Data Viewing & Monitoring

Monitoring is accomplished via the MicroServer which offers a variety of Internet and industrial protocols, datalogging capability, and ports for additional sensors such as wind, solar radiation, and/or precipitation sensors. Data can be downloaded for archival and analysis.

FTP output (XML and CSV) • XML web service • Internet browser user interface

SNMP, Modbus/OPC and RTU communication protocols are standard for Industrial Management applications.

Compatible with CWOP (Citizen Weather Observer Program) and Weather Underground, the MicroServer can automatically post data from your weather station to these network websites.
