The Variotec 460 Tracergas by Sewerin is great for leak detection on underground pipes by using non-combustible tracer gas. Using tracer gas is a tried and tested method of pinpointing leaks. It can be used in gas and water distribution networks, pipelines in buildings, heating systems, pressurized communication cables, gas-filled high voltage power lines and landfill sites sealed with double membrane layers. It can also be used to test for leaks in industrial products such as pipes, pumps, engine blocks and airfoils. Detecting gas leaks by tracer gas involves feeding a mixture of 95% nitrogen (carrier gas) and 5% hydrogen into the pipelines or other equipment/products being tested. The hydrogen escapes through the leak and is detected by the highly sensitive, specialized sensor. The low amount of hydrogen (just 5%) means that this method is safe: the gas is incombustible as per ISO 10156 thanks to the use of nitrogen as the carrier gas. It is non-toxic, and therefore also permitted for use in drinking water networks, as well as non-corrosive. Tracer gas is cheap and easy to obtain from technical gas or welding gas dealers. It is also environmentally-neutral and permeates all cover layers such as asphalt, concrete and other seal coats. Tracer gas always looks for the shortest route from the leak to the surface.
The low cross sensitivity of the gas-sensitive semiconductor when it comes to moisture and methane ensures a precise result and resolution down to 0.1 ppm H2. The Variotec 460 Receiver has a large display and a simple menu structure, making it easy to quickly obtain and analyze reliable results. In combination with the bell probe D80 you can achieve outstanding reaction times. With the expanded measuring range of the thermal-conductivity sensor, up to 100% volume H2 allows for further measuring functions. Measurement data can be saved and uploaded to a PC via USB connection.
