SI-100
Description
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
