The technology
Game Changing Methane Monitoring & Measurement

Using proprietary Quantum Lidar imaging, emissions are identified, quantified, and visualised with quantum precision to improve asset performance, manage operational risk, and support environmental reporting.

QLM Methane Camera · Fixed-site unit
Wide-area quantum lidar scanning
High-resolution detection and mapping across an entire site from a single fixed instrument.
Continuous monitoring
24/7 detection in all environmental conditions - events are caught the moment they start.
Source-level identification
Locate and quantify individual emitters so teams can act on the leaks that matter most.
Proven, defensible accuracy
Independently validated quantification regulators and operators can report with confidence.
From detection to action
Built for accurate, reliable methane monitoring.
DETECT
See the invisible
Continuous lidar imaging reveals plumes the instant they appear, no scheduled flyovers, no blind spots.
QUANTIFY
Measure with confidence
Every emission is located and sized in real units, producing defensible, audit-ready data.
ACT
Fix what matters
Automated alerts route the right teams to the biggest leaks first, cutting emissions and cost.
