    Tips: 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.

    Fixed Hydrogen Sulfide (H2S) Gas Detector
    Can your fixed hydrogen sulfide (H2S) gas detector work in biogas line, if yes, then what is the estimated lifetime of the electrochemical sensor?
    From: Blake | Date: 03/07/2019
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Yes, and the lifetime of electrochemical sensor is 2-3 years.
    Input Voltage of Hydrogen Sulfide (H2S) Gas Detector
    Can you provide fixed H2S gas detector but with 120V input voltage?
    From: Kiel | Date: 22/07/2019
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Hi, Kiel. The input voltage of this fixed H2S detector should be 24V DC, but you can use one of our switching mode power supply to convert 120V AC To 24V DC.
