AirLogics - Model AQS-1 -Dust Sentry Air Quality Monitoring System

• Real-time total VOCs (PID)
• Dust (PM2.5, PM10, TSP)
• O3, NO2, noise.
• Gravimetric sampling capabilities
• Light-weight lithium battery, solar power charging, or 110-power option
• Integrated weather station
• Light, mobile system

This equipment uses a proven near forward light scattering nephelometer and high precision sharp cut cyclone – with a measurement range of 0-60,000 μg/m3.

The patented sensor technology enables the AQS 1 to deliver data with very strong correlation to U.S. EPA approved monitors (Near Reference) over extended periods of time – several years with appropriate maintenance.  In head-to-head tests with traditional U.S. EPA-approved analyzers, the AQS 1 has shown R2 correlations as high as 0.98.

Key technology unique sets the AQS 1 apart in the industry:  

Pumped sampling system. This provides a steady flow of air to the sensor modules. It also allows for the use of filters which protect the sensors from airborne impurities – therefore extending their operating life.

Automatic Baseline Correction (ABC).  This technique sees the automatic correction of the ‘zero’ baseline every 60 seconds. The technique corrects for cross interferences and sensor drift – two of the biggest problems for sensor-based monitors.

Tried and tested PM sensing. A nephelometer made by Met One Instruments and custom-designed for the AQS 1. Compared to low cost optical counters, the Met One nephelometer is robust and proven to last for years in the field. In the AQS 1 the nephelometer is coupled with a pumped sampling system and an inlet heater which corrects for humidity interference.

Factory and Field Calibration. The AQS 1 sensor modules are calibrated against high purity gas standards prepared under ISO 6143 to ensure traceability to reference materials from National Metrology Institutes. The AQS 1 is field calibrated using the same standard reference materials as a US EPA / EU certified analyzer (i.e. calibration gas and dilution calibrators).

Live Dashboards

Our equipment transmits data in real time to a local computer or cloud-based server via telemetry.  Users can log-on to our customizable dashboards to view and manage the data.

Continous Data Collection and Logging

The monitoring data is automatically archived and used to generate summary graphs—daily, weekly, and/or at project completion.   The data is stored to  an on-site computer and to a secure, remote server maintained by Air Logics or to a secure cloud storage location.  The off-site, archived data provides redundancy of the collected dataset and offers clients convenient, remote access to project data via office computers and mobile devices.
