4HS+ Hydrogen Sulfide (H2S) Gas Sensor Part Number: 2112B2025 for Industrial Safety Monitoring

Key Features:

• High Reliability: Adopts mature 3 - electrode electrochemical technology, with low long - term drift and stable performance, which is in line with the reliability requirements of life - safety related detection equipment.
• Strong Environmental Adaptability: It can work intermittently in the extreme temperature range of -40℃ to +55℃ and adapt to most industrial and outdoor humidity environments without condensation.
• Easy Integration: No bias voltage is needed, and it only needs to be matched with a 5Ω load resistor to work normally. The lightweight (about 5g) and flexible installation direction make it easy to integrate into portable detection devices.
• Intrinsic Safety Performance: With limited maximum current and voltage, it meets the safety requirements of hazardous environments such as petrochemical and coal mine sites.

Purpose:

1. Industrial Safety Monitoring:

• Petrochemical plants, oil refineries, and natural gas processing facilities: Detect H₂S leaks during drilling, production, and transportation processes to protect on-site workers from toxic exposure.
• Coal mines and underground tunnels: Monitor H₂S concentrations in confined spaces where the gas is naturally occurring or generated by coal oxidation, ensuring compliance with mining safety standards.
• Metallurgical and chemical manufacturing: Used in processes involving sulfur-containing materials (e.g., smelting, wastewater treatment) to trigger timely alarms for H₂S over-limit situations.

2. Portable Safety Devices:

• Handheld gas detectors: Integrated into lightweight, battery-powered devices for field workers (e.g., maintenance technicians, emergency responders, and confined space entry teams) to enable on-the-go H₂S detection.
• Personal protective equipment (PPE) accessories: Paired with wearable safety gear to provide real-time H₂S concentration alerts for individual workers in high-risk environments.

3. Environmental & Compliance Monitoring:

• Wastewater treatment plants and sewage systems: Monitor H₂S emissions produced by organic matter decomposition, ensuring compliance with environmental protection regulations and minimizing odor pollution.
• Landfills and biogas facilities: Detect H₂S in biogas streams to protect processing equipment and ensure safe gas utilization or disposal.
• Ambient air quality monitoring stations: Supplement urban or industrial air quality networks to track H₂S levels from industrial emissions or accidental leaks.
