Hathorn Keyhole Gas Camera System

The Hathorn Keyhole Gas Camera System was developed to help utility professionals inspect active gas distribution lines without extensive excavation. Engineered for use with keyhole access methods, stuffing boxes, and traditional gas line insertion tools, the system allows technicians to navigate through tight bends and inspect gas mains ranging from small distribution lines to larger utility pipes.

Built for demanding field environments, the system combines a daylight-readable monitor, rugged aluminum components, onboard video recording capabilities, and long-distance push rods to simplify inspection and documentation. Available in multiple reel lengths, the system provides flexibility for a variety of municipal and utility applications.
