The HUNTER H₂ from Esders GmbH, is a professional-grade hydrogen tracer gas leak detector engineered for pinpointing even the smallest leaks in water and heating systems.
Designed specifically for water utility professionals and leak detection contractors, the HUNTER H₂ delivers exceptional sensitivity, rapid response times, and dual-sensor protection technology. It is the ideal solution when traditional acoustic or correlation methods fail, or cannot be used,—particularly for micro-leaks, plastic pipework, and challenging ground conditions.
By using safe, inert forming gas (5% hydrogen / 95% nitrogen), the HUNTER H₂ enables precise, non-destructive leak location in potable water networks, service connections, and heating infrastructure.
