1.2 Application
The gas leak detector GS 220 is the latest handheld gas leak detector. It indi-
cates 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 propane gas conduction.
