SI-100 Continous Gas Leak Detection : Fixed Gas Detector

SI-100 Gas Detection Equipment

SI-100 fixed gas detector is installed at places where potential gas hazard exits to measure gases such as oxygen, toxic gas and combustible gas (CH4, O2, CO, H2S, SO2, NH3, H2). 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.

SI-100 fixed gas detector is air, dust and explosion proof. It is certified with TRTS certification from Russia

The SI-100 fixed gas detector shows the concentration of gas and diagnostic result of the unit through its LCD display based on built in calibration mode.

There is also the option of an SI100C economy model without display

SI-100D is a fixed gas detector for monitoring LPG/LNG leaks in commercial kitchens.

Applications:

Steelworks, petrochemical, refining, shipbuilding, wastewater treatment plants and septic, mining, power, agency, confined space work area
