FAQs
1. Advantages of Optical Gas Imaging
Time-saving & Efficient: support large-scale real-time detection, rapid leak location, no need for interrupting production.
Long Range Detection: away from dangerous and complex areas, non-contact non-destructive testing, without additional radiation source
Easy to Analyze: intuitive imaging, instant storage, convenient analysis
Multi-function Inspection: a variety of gases can be detected, with excellent remote temperature measurement function
2.Working Principle of Optical Gas Imaging
Optical gas imaging is a kind of infrared technology that could see invisible industrial gases.
After absorbing infrared radiation at specific wavelengths, infrared radiation difference will cause between the gas and the background.
The gas leak detection infrared detector with built-in narrowband filter only receives the infrared band near the gas infrared absorption peak, and can convert the gas into visible infrared images through the radiation difference between the gas and the background.
