The EX-TEC HS product family helps the user clearly detect leaks in underground pipes.To avoid costly and time-consuming pointless excavations, it must be absolutely certain that the gas is actually leaking from a natural gas pipeline. Locating the exact position of the leak also ®keeps shaft work to a minimum. EX-TEC HS appliances offer new possibilities in this respect.If the gas has dispersed over a wide area, it is often difficult to pinpoint the leak exactly. In many cases the gas gathers under fixed surfaces and spreads over long distances.The optional oxygen sensor can also display the oxygen minimum at the same time as the methane maximum. This minimum, with its smaller diffusion area, is used to locate complex leaks more precisely.The integrated ethane detector easily picks up whether the gas is natural gas or swamp gas. The user does not need any extra accessories or specialist knowledge.®The EX-TEC HS 680/660 guides the user through the ethane analysis with prompts.The definitive result can be saved and further processed on the PC using the integrated USB port.

The VARIOTEC 4x0 range gives network technicians an efficient and cost effective means of carrying out all common measurement tasks in gas distribution networks.®The VARIOTEC 4x0 instruments utilise the same accessories and probes as previous generations of Sewerin gas measuring instruments so if you are upgrading there is no need to purchase new ones.The 480 EX and 460 EX can incorporate an optional ethane detector to quickly distinguish between natural and swamp gas. No more false indications from swamp gas rather than natural gas®All variants, except for the VARIOTEC 400 EX, can have optional oxygen and carbon monoxide sensors fitted.

Before making an expensive excavation you need to be sure the gas detected is really emanating from a natural gas pipe and that it is not swamp gas or coming from another gas source.

The VARIOTEC® 460 Tracergas was developed especially for leak detection on underground pipes by using tracer gas. It is characterised by an outstanding price to performance ratio.
The extraordinarily low cross sensitivity of the gas-sensitive semiconductor (SC) with regard to moisture and methane ensures an absolutely sure result and a resolution down to 0.1 ppm H2.
Thanks to an innovative operating concept, a large display and simple menu structure, device operators can quickly get reliable results.
In combination with the bell probe D80 you can achieve outstanding reaction times.
The expanded measuring range of the thermal-conductivity sensor, up to 100 % vol. H2 easily allows for further measuring tasks.
Save your measurements and transmit the results using the USB interface on the computer.
The 4 AA-size rechargeable batteries can be charged in just 3 hours and the operating time is at least 8 hours. As an alternative, you can use disposable batteries.

The PORTAFID® M3K portable flame ionisation detector is the perfect tool for above-ground inspections of underground gas lines. It is reliable and highly accurate, resistant to interference from moisture and only responds selectively to hydrocarbons. The PORTAFID® M3K features an 0.4 l fuel gas bottle, which is carried separately on the user's back.

The SNOOPER mini is a robust gas leak detector and is suitable for checking accessible gas lines for external leak tightness. Leaks are determined based on detection at connection points, e.g. fittings, flanges, threaded connections and gas regulator fittings The gas concentration is displayed in the ppm range. House lead-ins and concealed gas lines in enclosed spaces at air outlets can also be checked.
