I. Selection and Requirements for Detection Equipment
High-Precision Sensors
Prioritize gas detection devices with high-precision sensors (e.g., electrochemical sensors, infrared sensors, or hydrogen flame ionization detectors) to accurately capture minor concentration changes.
Use dedicated sensors for flammable/toxic gases (e.g., methane detectors, hydrogen sulfide detectors) and set alarm thresholds (e.g., methane: low alarm at 2%, high alarm at 5%).
Real-Time Monitoring & Portability
Ensure devices support real-time data feedback and rapid response to concentration changes (response time ≤30 seconds) to prevent safety risks from delays.
Use portable detectors with audible/visual alarms for confined spaces or temporary inspections (e.g., entering the receiver interior) .
Environmental Adaptability
Equipment must have waterproof/dustproof design (IP65 or higher) and withstand high temperatures, pressure, or corrosive environments for stable operation.
