320x256 / 30μm MWIR Cooled Optical Gas Imaging Camera for Visualizing Gas Leaks
With high performance signal processing circuit and advanced image processing algorithm, GAS330 cooled thermal module for gas leak detection is developed on the basis of HgCdTe mid-wave cooled infrared detector. By using the infrared thermal imaging technology, GAS330 can visualize the VOCs gas (volatile organic compounds) that can't be seen by naked eyes. It is effective to detect VOCs leakage in the production and transportation process of petrochemical enterprises, and has great application value in safety production, environmental protection supervision, cost saving.
High Sensitivity Detection
• Highly sensitive infrared detector, NETD≤15mK

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.
