Gx620f
Fixed-Mount Hydrocarbon/VOC Optical Gas Imaging (OGI) Camera
Product Variations
The Gx620f fixed-mount hydrocarbon/VOC OGI camera delivers continuous, automated gas leak detection for oil, gas, and chemical facilities. Using a cooled midwave infrared (MWIR) sensor and HD visual camera, it provides clear visualization of hydrocarbon and VOC emissions in real time. Certified for use in hazardous areas (ATEX, IECEx, ETL), the Gx620f integrates seamlessly with plant monitoring systems via GigE Vision or ONVIF to support 24/7 safety, compliance, and emissions-reduction goals.
Invisible leaks. Instantly visible.
Keep eyes on your most critical assets 24/7. The Gx620f continuously detects hydrocarbon and VOC leaks without sending your team into hazardous zones.
Dual infrared and HD video give you clear confirmation of leaks, making it easier to validate issues and share evidence across your operations team.
With ATEX, IECEx, and ETL certifications and a corrosion-resistant stainless-steel housing, the Gx620f is engineered to perform reliably in tough industrial conditions.
