Dräger GS3 Leak Detection

Pen-sized gas leak detector to find flammable gases such as natural gas, liquid gas, methane, propane or butane, even in hard-to-reach places. Detection of even the smallest leaks below 50 ppm with a detection range of 10,000 ppm. In addition to pipelines, it can be checked for leaks in closed systems. If detected, an audible signal will sound and an optical alarm will be given with the flashing red LEDs.

Leak detector the size of a pen

​Because the Dräger GS3 is the size of a ballpoint pen, it fits into any shirt pocket and can be easily stored and transported by the user. Its protective pouch also allows it to be easily attached to a belt and protects it against impacts.

Rapid leak detection

​The handy Dräger GS3 is quick to respond to flammable gases such as natural gas, liquefied petroleum gas, methane, propane or butane. It reliably detects even the smallest leaks. For example, for methane the sensitivity is below 50 ppm with a detection range of 10,000 ppm. In addition to pipes, this also allows containers and closed circuits to be tested for leaks.

Alarm function

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

Simple operation and handling

​The Dräger GS3 is self-explanatory and easy to operate. Its light weight of only about 50 g makes it particularly comfortable to use.

No maintenance required

​The Dräger GS3 calibrates itself automatically each time it is restarted. Since it calibrates itself automatically, maintenance is not necessary.

Simple operation

​The Dräger GS3 is self-explanatory and very easy to use thanks to its 1-button operation and handy size. By rapprochement to a leak and increasing gas concentration, the flashing and ticking rate will increase. By removing from a leak and decreasing gas concentration the signals will become slower. If the concentrations become smaller, the measuring range is automatically adjusted. The Dräger GS3 switches off automatically after 10 minutes of idle time.

Leaks can also easily be detected in hard-to-reach places

​Thanks to its small size, leakage locations can also quickly and easily be detected in hard-to-reach places.
