Safe. Efficient. Flexible.

The VARIOTEC® 660 combines maximum precision in leak detection with the flexibility required for the energy transition.

Flexible application

Whether classic natural gas network, pure hydrogen network or H₂ feed-in: the VARIOTEC® 660 reliably accompanies you through the transformation of gas networks.

Direct analysis

H2 and natural gas contents are determined directly on site and in the vol.% range - regardless of the type of natural gas for fast test processes and clear results.

Fast response

The VARIOTEC® 660 recognizes gas concentrations extremely quickly and precisely maps changes in the pipe network in the shortest possible time.

Wide range of applications

The VARIOTEC® 660 offers a universal solution for the professional inspection of above-ground and underground pipework systems. It is the ideal tool for network operators and service providers who want to safely convert their infrastructure to future-oriented 100% hydrogen or H2 feeds into the natural gas network. Whether for the detection of the smallest gas concentrations during leak detection or the precise testing of soil gas - the device delivers extremely fast and clear results under a wide range of conditions. The optional integrated ethane analyzer distinguishes between natural gas deposits and natural sump gas. Thanks to the compact design and short charging times, your teams remain mobile and highly efficient even during intensive working days. This ensures the integrity of your supply networks and effortlessly fulfills international safety standards and strict emission guidelines such as the EU Methane Regulation.
