Key capabilities and Technical Specifications

What makes continuous monitoring system the smarter choice

AIRMO system monitors methane emissions on your site continuously and directly. It operates 24/7, calculating emission rates from actual plume measurements - no reliance on weather models or assumptions. The modular system is quick to deploy, with automatic beam alignment and wireless operation.

Real-time leak detection

CMS continuously monitors air across a site using laser-based absorption spectroscopy. It detects abnormal methane concentrations with high sensitivity and sends instant alerts via SMS, email, or API.

Flux-based quantification

By scanning a laser beam across a fixed path, CMS creates a “flux plane” to directly measure the amount of methane moving through it. This allows for real emission rate estimates using mass-balance calculations, no need for dispersion models.

Smart event classification

Patented algorithms analyze high-frequency data to differentiate between intentional releases and unintentional leaks, minimizing false alarms.

System Components

No emissions missed? Here's how we deliver scalable, continuous monitoring

The AIRMO system is built for reliability at scale. With no moving parts in the sensor head, it’s self-monitoring and low maintenance, offering over eight years of service life. Fast response times and low operational costs make it ideal for proactive leak management. Designed for distributed coverage across large facilities or multi-site operations, it remains cost-efficient even in complex environments.
