HJK-VOC
The HJK-VOC employs a 320×256 cooled infrared sensor and integrates multi-sensor fusion technology. As a gas leak detection thermal camera, it enables rapid, non-contact scanning of storage tanks, pipelines, and other facilities to pinpoint VOC leaks accurately, significantly reducing revenue losses due to equipment failures and maintenance delays. As a cooled MWIR real-time gas leak detection infrared thermal camera for industrial inspections, it is well suited for demanding applications in petrochemical plants and environmental enforcement, where safety and efficiency are paramount. It is also an explosion-proof gas leak detection thermal camera for hazardous environments.

The HJK-VOC features AI-based real-time
leak labeling, laser methane detection,
4G connectivity, voice/fingerprint
recognition, and an explosion-
proof rugged design.
It is a reliable thermographic camera solution used in leak detection
and repair (LDAR), inaccessible point inspection, VOCs abatement,
and oil product storage, transport, and sales.
