Gas Hound


Industry standard for Comprehensive Integrity Management.

The CM202G "Gas Hound" is the first gimbal specifically designed for aerial gas leak detection and infrastructure integrity patrols.



The CM202G Gas Hound is a reliable, low cost and field-proven system for aerial gas leak detection and infrastructure integrity. Benefit from traceable and verifiable pipeline integrity data, rapid notification of anomalies, and precise geo-location of leaks, encroachments, environmental concerns, and right of way violations. High definition daylight footage is streamed simultaneously with Infra-Red leak detection data, which is all overlaid onto a GIS based mapping system, giving you prompt access to valuable information.


    • Niatros™ is designed for both fixed and mobile continuous monitoring applications to detect methane and other gas leaks in refineries, pipelines, storage facilities, and other installations.
  • Lower cost
  • Cutting-edge capabilities proven & documented with comprehensive field testing
  • Highly advanced imagery
  • Enhanced lens & electronics
  • Two-axis gyro-stabilized gimbal (pan & tilt capabilities)
  • The MWIR sensor is cooled to 80 K (-316 F) allowing the narrow band pass filter the ability to better eliminate other wavelengths that could interfere with the sensor images when inspecting a pipeline or station for gas leaks. The lens remains in focus throughout temperature changes.
