Product Introduction

Device 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.

Major Applications

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

Features

01. SI-100 measures the concentration of the flammable gas, toxic gas, oxygen and display with LCD

02. Easy magnetic bar operation

03. Big digital LCD installed with a blue back light

04. Explosive proof structure

05. Water/dust proof structure

06. Simple gas calibration

07. RUSSIA Goat-R Certification

08. EUROPE electromagnetic waves fitness Certification
