Focused Photonics Inc. (FPI) fortifies public health and environmental stewardship with its advanced Air Quality Monitoring Systems, delivering real-time insights into pollutants like O3, CO, NO2, SO2, PM2.5, and VOCs. Our AQMS series integrates UV, IR, and laser-based technologies for urban, industrial, and rural air surveillance, ensuring compliance with global standards.
Air quality monitoring quantifies atmospheric pollutants using a suite of optical and electrochemical techniques to measure gas and particulate concentrations. FPI’s AQMS systems employ UV Differential Optical Absorption Spectroscopy (DOAS) for NO2/SO2, Non-Dispersive Infrared (NDIR) for CO/CO2, laser scattering for PM2.5/PM10, and photoionization (PID) for VOCs, achieving sensitivities down to 1 ppb.
Rooted in early UV photometry, modern systems integrate IoT for real-time telemetry and machine learning for source apportionment. FPI optimizes with multi-wavelength calibration and temperature-stabilized optics, ensuring <2% drift per WHO guidelines. In 2025’s hyperlocal air quality push, our stations support mobile apps for citizen science and API feeds for smart city grids, reducing urban exposure risks by 20%.
FPI's systems fortify 6,000+ monitoring stations, with 1,500+ units deployed annually, shaping cleaner skies worldwide.
AQMS-300 tracks O3/NO2 in city grids, informing traffic restrictions. A 2024 Shanghai deployment cut smog episodes by 15% via predictive alerts.
AQMS-1000M maps VOC/PM from refineries, per EPA Method 325. A Sinopec site reduced benzene emissions by 30%, meeting fenceline standards.
AQMS-550 monitors PM2.5 in forests, aiding wildfire detection. A Yellowstone study tracked transboundary SO2, refining air shed models.
Portable AQMS-600 empowers communities with real-time PM/VOC data, integrated with wearables. A Delhi pilot boosted public compliance with AQI alerts by 25%.
These networks, synced via FPI’s cloud analytics, have informed 10+ national air policies, advancing SDG 11 sustainable cities.
With 22 years of optical mastery, 888+ patents, and WHO-aligned calibrations, FPI’s AQMS series delivers unmatched reliability and scalability.
FPI’s systems orchestrate pollutant profiling:
Ambient Intake: Multi-inlet manifolds sample gases and particulates, filtered for debris.
Sensing Synergy: Parallel UV/IR/laser modules quantify concentrations, cross-verified for accuracy.
Data Distillation: Edge AI filters noise, outputting AQI scores via MQTT protocols.
Actionable Analytics: Dashboards visualize trends, alerting via SMS for exceedances.
This clear conduit, mapped in our sensor array schematics, ensures actionable air insights.
