Leak detection

As large as a ballpoint pen, the Dräger GS3 locates leaks quickly and reliably, even in hard-to-reach places. The detector for combustible gases, such as natural gas and liquid gas, detects even the smallest leaks, which it indicates with an optical and acoustic signal.

Product Advantages

Fast leak detection

Whether natural gas, liquid gas, methane, propane or butane – the handy Dräger GS3 responds quickly to flammable gases. Even the smallest leaks are reliably detected. In addition to piping, other containers and closed systems can also be checked for leaks with ease.

Always on alert

To ensure that no alarm goes unnoticed, the Dräger GS3 not only has an acoustic alarm signal but also an optical flashing alarm.

Maximum security with minimum size

The leak detector is only the size of a ballpoint pen and can be stored compactly in any shirt pocket. This guarantees comfortable handling – and leak detection can also be carried out without difficulty in places that are difficult to access.

Maintenance free

The GS3 calibrates itself each time it is restarted. This eliminates maintenance.
