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 Micro IV is part of the personal protective equipment of firefighters and workers in mines, steelworks, refineries and canal construction. Thanks to its compact design and long operating time, it is a reliable 1-gas detector even for difficult conditions. The Micro IV monitors toxic gases, oxygen or hydrogen and alerts its wearer visually and acoustically. The data stored in the data logger can be read out conveniently via the infrared interface or a docking station.

The Micro IV has a slot for an electrochemical sensor. Smart Sensor technology allows for quick and easy sensor replacement. A wide range of EC sensors is available for a variety of toxic gases, hydrogen as well as oxygen with different measuring ranges such as ppm and vol.-%. This makes the Micro IV suitable for monitoring gas dangers such as ammonia, carbon monoxide, hydrogen sulphide, nitrogen and a lack or excess of oxygen. Optionally, an electric pump can be connected to safely clear confined spaces and containers.

Safety and operation
The Micro IV is certified for use in hazardous areas up to Ex zone 1. In addition, it is water- as well as dust-protected according to protection class IP54. The robust ABS housing is triple-metallised and additionally protected against shocks and vibrations by optional covers made of rubberised polycarbonate. The compact design, the very low weight and the carrying clip ensure optimal handling. Operation is done via three buttons and the illuminated display.

Alarm and battery life
In the event of a threshold being exceeded, the Micro IV warns its wearer with a light signal and loud horn (95 db(A)). The operating time with only one Mignon battery is up to 6 months. The optional pump has its own power supply and therefore does not shorten the running time of the unit.

With the docking station DS220, function tests, adjustment and documentation can be carried out for six Micro IV gas detectors. The G200 pump can be plugged in for free measurement. The DI220 readout device enables device configuration and data transfer to the PC. A complete overview of the accessories and all extensions offered for the Micro IV can be found at the bottom of this page.
