Product Description
YA-D400 Fixed H2S Hydrogen Sulphide Gas Detector
Professional industrial-grade fixed gas detection system for continuous monitoring of hydrogen sulphide (H2S) and other toxic gases in hazardous environments.
Product Overview
The YA-D400 series point-type gas detectors are engineered for reliable performance in chemical plants, petroleum facilities, metallurgical operations, liquefied gas stations, painting operations, and gas transmission systems. These industrial-grade detectors monitor toxic and combustible gases in both indoor and outdoor environments where gas leaks pose significant safety risks.
Key Features
- Real-time gas concentration display with large, clear backlit screen
- Triple alarm system: fault, low-level, and high-level alerts
- Infrared remote control operation for safe, non-contact adjustments
- Multiple communication protocols: RS485, two-wire bus, LoRa, and 4-20mA output
- Three relay outputs (250V 5A) for automatic control of ventilation systems
- Data logging with storage for 40 high and low alarm records
- Unit conversion capability for toxic gases between mg/m³ and μmol/mol
- High-performance ARM microprocessor for advanced processing
