Description

Forming gas has been used for a long time to locate leaks that cannot be found with the standard methods, electro-acoustic leak detection or correlation. With this method (also called tracer gas), the gas (5 vol.% hydrogen and 95 vol.% nitrogen) is injected into the pipeline under pressure.

It is then transported through the water pipe and escapes through the leak after a short time. The hydrogen contained in the forming gas is lighter than air and rises upwards. At the surface, it can be easily detected with the HUNTER Tracer Gas and corresponding probes and the leak can be localized in this way. The method offers advantages when acoustic methods reach their limits, e.g. due to increasing noise pollution from road traffic and plastic pipelines. It also saves expensive and time-consuming excavations at suspected leakage points.

The new HUNTER Tracer Gas is the consistent further development of our previous popular model. We have retained the proven technology, e.g. the semiconductor sensor for the gas detection range. This means that a very fast reaction time and stability of the measured value are still achieved, so that even the smallest spread of gas can be reliably detected. For better readability, the device has a significantly larger display with higher resolution. In addition, the communication options via Bluetooth have been expanded to enable a connection to our online portal Esders Connect.
