Device description

SL-101 is a fixed gas detector installed in a place where potential gas hazard exists to measure oxygen, toxic gas and combustible gas. It hows not only the concentration of gas but also iagnostic result of the unit itself through the LCD display and can be connected to the controller with RF commucation wirelessly.

Major Applications

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

Features

01. Easy Installation/removal because no wiring works are required

02. Economic system which doesn’t require any wiring construction

03. Water/Dust proof structure

04. Same functions with Fixed Gas Detector working with wiring electrical power source

05. Tracking is possible with its own address

06. Maintenance and Replacement are simple
