Wohler GS 220气体嗅探器

The Wohler GS 220 is a highly sensitive and quick responsive Gas Sniffer to control tightness and to detect leakage of gas lines. The LEDs and the acoustic signal, which can also be heard over head phones, indicate even the smallest leaks. The Wohler GS 220 has a 440 mm flexible gooseneck that helps to access hard to reach spots. The Wohler GS 220 Gas Sniffer indicates the volume of the gas concentration of methane and propane in LEDs by stage (40 ppm to 640 ppm). The instrument is perfect for the control of gas lines carrying combustible gases.
