GS+7H2S Hydrogen Sulfide (H2S) Sensor For Industrial Safety Industrial General

Working Principle:

The GS+7H2S sensor operates based on the electrochemical three - electrode principle. Hydrogen sulfide gas diffuses through a permeable membrane and reacts with chemicals at the working electrode, while oxygen reacts at the counter - electrode. These reactions release charges to form a current, and the magnitude of the current is proportional to the hydrogen sulfide concentration. By measuring the current, the concentration of hydrogen sulfide can be determined.

Key Features:

  • High stability, ensuring accurate and reliable measurement results over an extended period.
  • Fast response and recovery, enabling quick detection of hydrogen sulfide and a rapid return to the baseline after the gas is removed.
  • Robust environmental stability, allowing it to function properly in a variety of environmental conditions, including different temperatures and humidity levels.

Common Applications:

  • Industrial Safety: Used to detect hydrogen sulfide in industrial production processes to safeguard the safety of workers and equipment.
  • Industrial General: Such as in petrochemical plants, refineries, and other industrial sites to monitor hydrogen sulfide emissions and ensure compliance with environmental regulations.
