    Hydrogen Sulfide (H2S) Gas Detector Applications

    Hydrogen sulfide (H2S) detector with pump-suction style is used to monitor the concentrtion of H2S in the dangerous areas like oil recovery, petrochemical, metallurgy, sewage treatment, exhaust emission, chemical, agriculture, refinery and so on.hydrogen sulfide H2S gas detector applicationsTips: Installation of Fixed Hydrogen Sulfide (H2S) Detector

    Fixed hydrogen sulfide (H2S) detector shall be installed in the areas which are easy to release and gather the hydrogen sulfide gas, such as the drilling site, downhole operation site, gathering station, natural gas evolution field, water treatment station and refinery area.

    The mounting site of fixed-type H2S detector should be determined by on-site facilities, processes, and the diffusion and gathering of hydrogen sulfide gas.

    The fixed hydrogen sulfide (H2S) detector should be installed below the release source, and it shall be within 2m outside and within 1m inside. Moreover, the detector is better to be installed at 0.5-0.6m away from the gas release source. The installation height shall be 0.3-0.6m higher than the ground or floor. If the detector is installed lower, it’s easy to be affected by the rain drops, which may damage the detector.

    If possible, please select the gas detectors with concentration display and acousto-optic alarm. The operators can observe the existence of hydrogen sulfide gas on site without returning to the duty room to see the alarm controller. It is finally better to protect them.

    This video will show you the basic settings of ATO portable gas detectors including high/low alarm setting, language setting and time setting.
