3. Product parameter

Infrared imaging gas detection module index are as follows:
 
Note:
[1] : Infrared imaging gas monitoring module prototype products are mainly methane leakage monitoring, in addition to methane can also detect a variety of hydrocarbons and VOC gases;
 
[2]: The operating temperature of the camera is limited by the operating temperature of the infrared detector, which requires thermal control design;

4.Product characteristics

Can achieve a variety of gas detection:
  • Alkane gases: methane, ethane, propane, butane, n-pentane, isopentane, etc.
  • Olefin gases: ethylene, propylene, butadiene, etc.
  • Aromatic hydrocarbon gas: benzene, toluene, xylene;
  • Others: methanol, ethanol, acetic acid, etc.
  • Wide monitoring area;
Quantitative visualization of gas leakage;
Quickly locate the source of the leak;
