  3. W: P: 503-629-0887 E: 3 The Orion AQM series professional air quality monitoring systems provide for immediate, on- site data for analysis, compliance, and decision- making. Near reference measurement performance offers significant value over traditional AQ monitoring. All models include the basic meteorological parameters of temperature, humidity, and barometric pressure. New Value in Air Quality Monitoring Measurement performance is based on proprietary advanced algorithms that enable parts per billion (ppb) measurements at an affordable price by using electrochemical sensors. Using the met sensor data, the algorithms compensate for the impact of ambient conditions and aging on the sensor elements and remove the need for costly gas sampling and maintenance equipment.

  6. W: P: 503-629-0887 E: 6 The Orion AQM is specifically designed for air quality monitoring networks in urban areas, road networks, or around industrial sites and transportation hubs. Thanks to its small weight and compact size, the Orion AQM is ideally suited for deployment even in large air quality networks. Monitoring is accomplished via the Weather MicroServer which receives the measurement data via a serial connection. Easy to Deploy Networks The MicroServer calculates sensor averages and air quality index (AQI) for all the parameters. The data is stored in data log files (CSV format) on a one-minute interval with a one-year storage capacity. The MicroServer can upload the data to the Internet including our CWS Cloud Weather Server.

  11. W: P: 503-629-0887 E: 11 Sensors Gas Measurement Technology The gas measuring technology is based on proprietary advanced algorithms and electrochemical technology. The sampled gas causes a reduction or oxidation reaction in an electrochemical cell. Both reactions create a weak electric current. The electric current is directly dependent on the volume of measured gas. By measuring the electric current and using advanced calculation and compensation algorithms, the AQM-Gas calculates the gas content. Most electrochemical cells are highly susceptible to ambient conditions (temperature and humidity), but the AQM-Gas reverses the impact with a proprietary adjustment and compensation system, which guarantees accurate ppb measurements. The electrochemical cells require a stabilization period of at least 24 hours after switching the device on before using the measurement results. To ensure optimal measuring accuracy, a 48-hour stabilization period is recommended. The devices take measurements during the stabilization period, but the measurements are marked as invalid.

  26. 26 Maintenance & Calibration Clean the device as needed. With large amounts of fine dust, for example sand or smoke particles, it is necessary to check the condition of the device more often and take the necessary actions to keep the device clean. When the device health is lower than 30%, it is recommended to send the unit in to have the electrochemical gas sensors replaced. Maintenance tasks can be performed by a qualified technician, or the module can be returned to the factory for service. W: P: 503-629-0887 E:
