VARIOTEC 660 — reliable natural gas and hydrogen measurement

Pipeline inspection in natural gas and hydrogen networks

The VARIOTEC® 660 is a combined gas measuring instrument for professional inspection of pipelines in natural gas and hydrogen networks. Highly sensitive sensor technology enables the simultaneous measurement of methane and hydrogen, allowing efficient determination of hydrogen concentrations across different natural gas qualities. Its robust design and ATEX-certified explosion protection make the instrument ideally suited for daily use by gas utilities and service providers. Benefit from rapid leak localisation and straightforward documentation of inspection processes. Optional ethane analysis allows reliable differentiation between natural gas and swamp gas.

Safe. Efficient. Flexible.

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

Flexible application

Suitable for conventional natural gas networks, pure hydrogen networks and hydrogen blending

Direct analysis

Hydrogen and natural gas content is determined directly on site in the vol.% range, independent of gas quality

Fast response

Gas concentrations are detected extremely quickly, enabling precise mapping of pipeline changes

Wide range of applications

The VARIOTEC® 660 offers a universal solution for professional inspection of above-ground and underground pipeline systems. It is the ideal tool for network operators and service companies preparing their infrastructure for future-ready 100% hydrogen operation or hydrogen injection into natural gas grids. Whether detecting very small gas concentrations during leak surveys or performing precise soil gas measurements, the instrument delivers fast and reliable results under a wide range of conditions. Optional ethane analysis reliably distinguishes natural gas leaks from swamp gas. Compact design and short charging times ensure high mobility and efficiency while supporting compliance with international safety standards and regulations such as the EU Methane Regulation.
