Wohler 6606 - GS 220 Gas Sniffer

The Wohler GS 220 gas leak detector is the latest in handheld gas detection. It indicates leaks through a 5 level LED alarm, as well as an acoustic signal. Areas which are difficult to access can be reached with a 440 mm long flexible probe.

The GS 220 shows the concentration of methane and propane gas from 40 ppm up to 640 ppm, with both an audio and visual signal. The GS 220 is a gas leak detector, and as such it detects leaks, but it does not measure the exact concentration of gas. Signals are shown in a 5 level LED, as well as a beeping sound which increases and decreases in frequency, according to gas levels.
