Methane may appear as a byproduct or fuel; CH4 connections are often located in hard-to-reach areas. Legacy method 21 sniffers are slow and hazardous to operate in such locations. Camera leak detection enables safe-distance scanning from ground level, with zoom and high-resolution sensors identifying leaks at tens of meters.Visualizing the Invisible DangerMany VOCs are toxic or ...

For EPA Appendix K compliance, higher sensitivity is essential to ensure comprehensive detection.From Qualitative to Quantitative: The QOGI RevolutionQuantitative Optical Gas Imaging (QOGI) enables real-time mass flow estimation of leaks, reducing reliance on post-process sniffers. Under MERP, the cost of methane emissions is rising from $900 per metric ton in 2024 to $1,500 per ...

The Efficiency Trap Manual OGI surveys, while more efficient than legacy sniffers, still require substantial organizational resources. Accessing hard-to-reach connectors often demands permits, scaffolding, or shutdown workflows, slowing inspection velocity and increasing the Man-Hours per Survey (MHPS). ...

OGI - short for Optical Gas Imaging - has rapidly become a cornerstone of modern emission monitoring and leak detection strategies. As regulatory pressures increase and industrial operations seek better tools to manage fugitive emissions, OGI stands out for its precision, efficiency, and visual clarity. For over a decade, OPGAL has been at the forefront of OGI technology, delivering ...

StomaCloak’s fabric traps and changes odor molecules, significantly reducing waste odor (as demonstrated in a recent scientific study involving sniffer dogs). StomaCloak also wicks moisture to keep skin healthy and provides the first defense against leaks. ...
One of the major regulatory impediments for fully accepting the OGI technology as an alternative and superior LDAR practice, is the lack of rigorous understating of the technology’s envelope of sensitivity performance, compared to the volumetric concentrations provided by the traditional PID/FID-based “sniffers”. This extended abstract summarizes the tested ...
