Leak detection

Only as big as a pen, the Dräger GS3 also quickly and reliably detects hard to access leaks. The detector for flammable gases such as natural gas and liquefied petroleum gas detects even the smallest of leaks through an optic and acoustic signal.

  • Maximal safety with minimum size
  • Rapid leak detection
  • Always ready
  • Maintenance-free


Detectable gases include natural gas, methane, liquefied petroleum gas, propane, butane, petrol, kerosene, alcohols, various solvents, acetone, and hydrogen.

To ensure that no alarm goes unnoticed, in addition to an acoustic signal the Dräger GS3 also features a visual alarm with red flashing LEDs.

The Dräger GS3 is self-explanatory and very easy to use thanks to its 1-button operation and handy size.

The GS3 has an operating time of up to 6 hours. The batteries (2 microcells AAA) can easily be replaced through the battery compartment.

Leak detector the size of a pen

The leak detector is as small as a pen, ensuring convenient handling. Leaks can also easily be detected in hard to access areas. The size ensures you can have the Dräger GS3 handy at all times and can, for example, conveniently stored in a shirt pocket.

Product description

The handy Dräger GS3 is quick to respond to flammable gases such as natural gas, liquefied petroleum gas, methane, propane, or butane. Even the smallest leaks are dependably traced. With the function ‘zero’, rising gas concentrations can also be pinpointed. In case of dropping gas concentrations, the zero point is automatically added. In addition to pipelines, this also allows containers and closed circuits to be tested for leaks.

Each time it is restarted, the GS3 calibrates itself. So, it requires no maintenance work.

It has the size of a pen and is equipped with the latest technology, the GS3 fits into the durable belt pouch that comes with it.
