SI-200E

Diffusion Type Fixed Gas Detector

SI-200E is a fixed gas detector designed for installation in areas with potential gas hazards. It measures oxygen, toxic gases, and combustible gases, and displays both gas concentrations and self-diagnostic results via its LED display. SI-200E can be connected to a controller using standard 4–20mA analog output or RS-485 digital communication. Bluetooth connectivity also allows for convenient configuration and input settings.

KEY FEATURES
    • Explosion-proof Certification: Approved for ATEX, IECEx, and CE
    • 4-digit Digital Concentration Display: Provides accurate gas concentration readings
    • Various Communication Interfaces Supported: 4-20mA output and RS-485 communication
    • Wireless Connectivity: Real-time data transmission to mobile devices
    • Robust Design: Withstands harsh environments and hazardous areas
    • Advanced Detection Technology: Provides excellent performance
