SI-100 is a fixed gas detector installed in a place where potential gas hazard exists to measure oxygen, toxic gas and combustible gas. It shows not only the concentration of gas but also diagnostic result of the unit itself through the LCD display and can be connected to the controller with a standard 4-20mA analog output communication or RS-485 digital communication.

Key Feature
⇒ SI-100 measures the concentration of the flammable gas, toxic gas, oxygen and display with LCD
⇒ Easy operation with a magnetic bar
⇒ Big digital LCD installed with a blue backlight
⇒ Explosive proof structure
⇒ Water/dust proof structure
⇒ Simple gas calibration
