For more than 60 years, GfG has been committed to protecting people, industrial facilities and the environment by developing and manufacturing gas detection systems. With an extensive range of portable gas detectors and fixed gas detection systems, GfG can supply you with a selection of products for many applications and industries. Our scope also includes on-site service and advanced training courses.


What distinguishes us from other manufacturers

We are specialists for gas detection solutions, not generalists in safety. No one can be the best at everything, but if you focus on one thing, you can achieve excellence. We work hard to provide you with the best gas detection equipment available, so you can focus on your task without having to worry about the risks that gases can pose. Because of that we invest more heavily in research and development than any other company. Approximately 13% of our annual turnover is reinvested in basic research and the development of new sensors and devices.


A “never say no” approach

This includes finding solutions for customers whose requirements are not met by “off the shelf” products. We take pride in our longstanding cooperation with the Singapore Civil Defence Force (SCDF), for example. For many years now, they have put their trust in GfG’s portable devices, which we optimized to adapt to the Singaporean climate and fulfill the special requirements for integration into the SCDF communication network.

The G400-MP2 is attached to a G450 or G460. When the pump is switched on, the diffusion openings of the gas detection device are covered so that the measurement results are not influenced by the ambient air. Faults in the pump are also indicated on the gas detector’s display thanks to smart communication with the gas detector. The pump’s own power supply ensures that the gas detection device’s battery life is not shortened during pump operation.

Equipment and technique
Thanks to the high under-pressure performance, confined spaces such as ducts, cellars and tanks can be cleared from a safe distance before and while they are entered by people with portable gas detection devices. The flow rate is up to 0.5 liters per minute. With an alkaline battery, 10 hours of continuous operation of the pump is possible, with NiMH battery even 12 hours. Like the G450 and G460 gas detection devices, both the battery and the rechargeable battery are approved for Ex zone 1.
