Portable Instruments

GfG portable instruments are the smallest measuring instruments for personal safety available. They offer increased safety and simple operation. Portable instruments are divided into two different categories:

                  • Single-gas Detectors
                  • Multi-gas Detectors
Multi-gas Detectors
Multi-gas detectors monitor several gases simultaneously, ensuring employees' safety with a compact instrument.
