Fixed Gas Detection


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 RS485 digital communication.

Key Feature
⇒ Various sensors can be applied
⇒ Easy operation with a magnetic bar
⇒ Large digital LCD installed with a blue backlight
⇒ Explosive proof structure
⇒ Water/dust proof structure
⇒ Automatic calibration function
⇒ Long-distance transmission by 4-20mA output
