Multi-Gas Module

The Clarity Multi-Gas Module is designed to detect a configurable set of gases depending on your project needs. Common options include nitrogen dioxide (NO₂), carbon monoxide (CO), and ozone (O₃). This allows for targeted monitoring of pollutants from traffic, industry, and combustion sources.

Yes — the Multi-Gas Module is modular by design. Customers can select specific gases to monitor based on local emission sources, regulatory requirements, or community health concerns. This flexibility makes it ideal for both research-driven deployments and operational air quality management programs.

The Multi-Gas Module enhances Clarity deployments by adding gaseous pollutant data to existing PM or black carbon measurements. When paired with the Node-S, it helps build a fuller picture of air quality by capturing both particle and gas-phase pollutants, enabling better source attribution and response planning.

Industries such as transportation, mining, oil and gas, utilities, and manufacturing use multigas monitoring to track emissions and protect worker and community health. Urban planning agencies and environmental regulators also rely on multi-gas data to inform clean air policies and evaluate the effectiveness of mitigation strategies.

While the Multi-Gas Module is rugged and weatherproof, it is designed for ambient outdoor monitoring — not for hazardous confined spaces or explosive-risk industrial environments. For those settings, intrinsically safe equipment may be required. That said, the module performs well for perimeter monitoring or fenceline applications in industrial zones.

We recommend periodic recalibration depending on pollutant type, deployment conditions, and data accuracy requirements. Clarity offers optional Calibration and Validation Services and automated QA/QC workflows to help maintain reliable performance over time. Note that collocation is currently required for the Multi-Gas Module.
