Methane (CH₄) Monitoring with Aeroqual AQS 1 & AQM 65
Methane Monitoring with Aeroqual AQS 1 & AQM 65
Bottom line up front: For fast, defensible perimeter methane monitoring, Specto’s CH₄ Module inside the Aeroqual AQS 1 or AQM 65 provides reliable performance: 0–500 ppm range, 0.01 ppm resolution, 0.04 ppm limit of detection, and integrated zero cycling that keeps drift to ~0.04 ppm (24 hr). With cellular telemetry and solar options, you can be operational the same day.
What is methane monitoring?
Methane monitoring is the process of continuously measuring ambient CH₄ concentrations around facilities such as landfills and oil & gas sites. Using the Aeroqual AQS 1 or AQM 65 with Specto’s methane module ensures real-time, defensible data with NIST-traceable calibration and low drift—critical for compliance, emissions reduction, and safety programs.
Why choose Specto’s turnkey methane monitoring solution?
- Continuous measurement: Reliable fence-line CH₄ data 24/7.
- Compliance support: Meets regulatory needs (e.g., Colorado Reg 7, California SB 1137).
- Fast deployment: Pre-configured by Specto with telemetry, power, and cloud integration.

FAQs on methane monitoring
How fast can I deploy a system?
Specto ships pre-configured methane monitoring stations so you can commission in hours, avoiding long international lead times.
Is the data defensible for compliance?
Yes. Published specs, NIST-traceable calibration, and integrated zero cycling provide reliable records for stakeholders and regulators.
Can I expand beyond methane later?
Absolutely. The AQM 65 makes it easy to add PM, meteorological sensors, and other gas modules.
