Frequently Asked Questions
Advantages of Optical Gas Imaging
  • Time-saving & Efficient: supports large-scale real-time detection, rapid leak location without interrupting production
  • Long Range Detection: operates away from dangerous areas with non-contact, non-destructive testing
  • Easy to Analyze: intuitive imaging with instant storage and convenient analysis
  • Multi-function Inspection: detects various gases with excellent remote temperature measurement
Working Principle of Optical Gas Imaging
Optical gas imaging is an infrared technology that visualizes invisible industrial gases. After absorbing infrared radiation at specific wavelengths, infrared radiation differences occur between the gas and background. The gas leak detection infrared detector with built-in narrowband filter receives the infrared band near the gas infrared absorption peak and converts the gas into visible infrared images through radiation differences.
