Investigator Gas

Piloted in Northern Gas Networks (UK), in 2013 JD7 commercially launched its live gas insertion system capable of 100m travel.  This technology incorporates not only high resolution CCTV camera sensors but also a highly sensitive acoustic sensor coupled with a sonde. The acoustic sensor is used for precise leak detection pinpointing in all materials and pressures.

Investigator Light

The JD7 Investigator LightTM is a fully integral pressurized pipe inspection and leak detection system designed for harsh environments. Designed for 3in. diameter pipework and above for complete asset condition examination and leak finding. Access through fire hydrants, 1.5in. and above pressure fittings, air valves, gate valves and Quadrina’s at full mains pressure.
