Product Characteristics

High measurement accuracy
The sensor adopts import gas sensitive components with the characteristic of high accuracy, strong reliability, quick response and renewing time, strong anti-jamming and easy to choose gas.
Intuitionistic and clear shows
Using large liquid crystal screen, show the gas concentration, range and present time; the buttons using touching way, working with multiple icon of the display makes the operating more sententious.
Low consumption
Small volume, light weight, low consumption.
Proof explosion
Intrinsic safetystructure can be used in dangerous 1,2 areas.
High response speed
Imbibing working principle makes the response speed faster.
Long working time and life
Selecting high-powered nickel battery with long working time. Also using electrification protection and low pressure, which ensures the battery more reliable and long using life

Working principle

The detector adopts pump absorption way to do sampling of the measure combustible gas. The sensor changes the concentration of the sampling gas into electric quantity signal. After magnifying of the signal, send it to the MCU to complete the concentration measurement and display.
