Description

Features

  • Modular internal structure:
    • Implemented modular internal structure design, securing a patent for the structural layout.
    • Divided into 3 detection modules, with each capable of identifying up to 6 gases.
  • Accommodates up to 18 gas detection configurations.
  • The independent modules segregate air intake to prevent gas interference and enhance detection precision.
  • Flexible, multi-pump system:
    • Employs a versatile air supply system with up to three pumps, enabling pump switching to prevent cross-gas contamination, thereby extending sensor lifespan.
  • 3.5 inch high-definition colour screen:
    • Crafted from durable aviation-grade material.
    • Utilizes a 3.5-inch high-definition colour screen with excellent resolution and broad viewing angles.
  • High configuration control core:
    • Incorporates industrial-grade sensors imported for superior performance.
    • Features a large-size high-definition display, enhancing control system capabilities and user experience.
  • Multiple display modes coexist:
    • Offers various display modes, including gas concentration data display and real-time gas concentration curve display, with seamless switching.
  • Optional features:
    • Provides the option for a built-in thermal printer, facilitating mobile printing as needed.
    • Offers an add-on high-temperature probe capable of withstanding temperatures up to 1200°C.

 

Technical Specification

Gas Detected H2 CH4 O2 CO
Detection principle CH4/CO: Infrared principleO2: Electrochemical principle H2: Heat Conduction principle
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.
