SI-200E

Diffusion Type Fixed Gas Detector

DESCRIPTION

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 4–20 mA analog output or RS-485 digital communication. Wireless connectivity allows for convenient configuration and input settings.
