The Gastec HS100 Hydrogen Sulphide Sensor represents a sophisticated approach to electrochemical gas detection. By employing the controlled potential electrolysis method, the sensor maintains a specific electrochemical state that allows for the highly selective oxidation of $H_2S$ molecules. This process generates a current flow directly proportional to the gas concentration, ensuring linear and predictable data output for your monitoring systems.
One of the standout advantages of the HS-100 series is its structural integrity and precision-engineered circuit board integration. The HSS-1050HL variant is optimized for long-term stability, reducing the frequency of calibration and maintenance. Whether used as a replacement part or integrated into a new OEM system, this sensor provides the reliability that engineers and safety officers require to protect personnel and infrastructure from the hazards of Hydrogen Sulphide.
The Gastec HS100 Hydrogen Sulphide Sensor is a high-precision analytical component engineered for the continuous and accurate detection of Hydrogen Sulphide ($H_2S$) in industrial environments. Utilizing advanced controlled potential electrolysis, this sensor delivers exceptional sensitivity and stability, making it a critical asset for safety-critical gas monitoring systems.
Although, technology is always evolving, one demand on our products never changes: the demand for customer safety. Whenever we contribute to customer safety, we are presented with an opportunity to develop further.
GASTEC holds this corporate creed of safety and development in high esteem, as it strives to grow while always putting customer safety first.

The HS-100 is a “consumable” analytical part. Over time, the internal electrolyte can be depleted or the gas-permeable membrane can become clogged by environmental dust or oils.
Technical Tip: If your HSS-1050HL analyzer is providing sluggish readings or can no longer be calibrated to the span gas, the HS-100 sensor is likely reaching its end-of-life. After installing a new HS-100, always allow at least 12 to 24 hours for the sensor to stabilize (electrically polarize) before performing the final calibration.
The Gastec HS100 Hydrogen Sulphide Sensor is ideally suited for various industrial and safety applications, including:
