商品詳細介紹Product Introduction

 SI-200E/A Diffusion Type Fixed Gas Detector

The SI-200E/SI-200A series explosion-proof fixed gas detectors are designed to detect the concentration of oxygen, combustible gases, and various toxic gases in the environment. When the concentration of the target gas in the atmosphere exceeds the alarm set point, an alarm is triggered, and the corresponding alarm LED light will illuminate. The device features an alarm delay function that can be configured based on the site conditions. In addition to the 4-20 mA industrial standard output, the device also offers RS485 output and three alarm relay outputs, with an optional HART module available. Regular maintenance, impact testing, calibration, and settings can be performed via a magnetic stick, physical button, or Bluetooth, making it easy to operate without the need to open the cover.
