Leak Detection Game-Changer

Clearly visualize and precisely locate gas leaks in a safe, efficient and cost-effective manner. Reduce harmful gas leaks, increase efficiency, limit product loss and protect lives. Sierra-Olympic’s Ventus OGI 640 x 512 optical gas imaging camera is in a class of its own as the smallest, lightest, highest-resolution and most powerful camera of its kind on the market.

Ventus OGI 50 mm
11 ° FOV optimized for longer-range leak detection applications including ground-based fixed mounted systems as well as airborne systems including fixed-wing aircraft from above 1,000+ ft.
Ventus OGI 25 mm
21.7 ° FOV optimized for closer-in applications where a wide field of view is ideal, including UAV/UAS, handheld units, fixed mounted and ground-based robotics applications.
