H2 Tracer Gas Water Leak Detector

The Sewerin Variotec 460 Tracer Gas Leak Detector is designed to locate leaks where acoustical systems cannot, such as extremely deep pipe, loud industrial sites, etc., or where newly installed water pipe systems are failing air pressure testing. Detecting water leaks using tracer gas involves feeding a mixture of 95% nitrogen (carrier gas) and 5% hydrogen (H2) into the pipe. The H2 gas escapes through the leak and is detected above ground by the highly sensitive, specialized sensor. H2 tracer gas is non-toxic and non-corrosive, therefore permitted for use in all drinking water systems. H2 tracer gas is environmentally neutral and permeates all cover layers such as asphalt, concrete and other seal coats. Hydrogen (H2) is the lightest and smallest known element on the periodic table, therefore it will always take the shortest route from the leak in the pipe to the surface, making pinpointing on any surface possible.
