Gas Detected

O2 CO2 CO CH4

Detection principle

CH4/CO/CO2: Infrared principle

O2: Electrochemical principles

Sampling method

Built-in stable flow pump, each flow pump is equipped in each independent module, pump flow is adjustable in ten steps, flow

range: 0-800 mL/Min

Modular structure

3 detection modules, each module can be selected to detect up to 6 kinds of gases, and a total of 18 kinds of gases can be selected. The independence between the modules can solve the problem of

mutual interference between gases to the greatest extent.

Concentration unit

ppm, mg/m3, %VOL, %LEL, can be switched by one button, and the concentration value is automatically converted by the internal

system
