1.2 Application
The gas leak detector GS 220 is the latest handheld gas leak detector. It indicates
even smallest leaks by an LED-Leak alarm and an acoustic signal that can also be
heard with an earphone. Areas that are difficult to access can be reached with a 440
mm long flexible probe.
The Wöhler GS 220 shows the concentration of methane and propane gas from 40
ppm up to 640 ppm. Therefore, the device is ideal for the control of methane and pro-
pane gas conduction.
