Water Leak Detection using Tracer Gas
If a water pipe is not under pressure or the noise from the leak cannot  easily be  heard then Tracer gas can be a very useful technique to locate water leaks in: Customer Supply Pipes, Underwater Heating Systems, Boilers, Central Heating Systems, Mains Distribution Networks.

The Tracer gas is introduced into the pipe with the leak from a cylinder of gas. The tracer gas used to find water leaks is a mixture of hydrogen (5%) and nitrogen(95%) making it completely safe to use in drinking water supplies being both non toxic and non corrosive. The tracer gas contains hydrogen, which is the the lightest and smallest molecule in the atmosphere, which will exit at the leak point and make its way to the surface where it is detected by the highly sensitive Variotec 460 gas detector.
