The OLLI Tracer Gas from Esders GmbH, is a high-performance gas leak detector designed specifically for professional tracer gas leak detection in drinking water distribution systems.
Engineered for utility contractors, water companies, and leak detection specialists, the OLLI Tracer Gas enables rapid and precise location of even the smallest leaks using forming gas (5% hydrogen in 95% nitrogen). Where acoustic leak detection methods fall short—particularly on plastic mains, large-diameter pipes, or low-pressure systems—the tracer gas method provides a reliable, cost-effective alternative.
Forming gas is odorless, non-toxic, non-flammable and non-explosive, making it safe for use in live drinking water networks. Once introduced into the pipework, the hydrogen component rises to the surface and is detected with high sensitivity by the OLLI’s integrated sensor and internal pump system.

Built for demanding field conditions, the OLLI features an ergonomic, impact-resistant 2-component housing with IP67 protection. Its high-contrast, backlit LCD graphic display ensures clear visibility of measured values in all working environments—from underground chambers to roadside inspections.
With Bluetooth connectivity, long battery life, and intuitive menu navigation, the OLLI Tracer Gas is a complete professional solution for modern water loss management and non-acoustic leak detection.
