LWIR Cooled Optical Gas Imaging Camera 320x256 for Visualizing SF6/NH3 Gas
Sulfur hexafluoride (SF₆) is commonly used in high-voltage power equipment and has a strong greenhouse effect. Ammonia, as a widely used refrigerant in industrial refrigeration systems, is highly toxic and volatile.
The LFD330C2 infrared detector for gas leak detection is developed based on Type II superlattice (T2SL) technology, delivering exceptional performance in sensitivity, stability, and integration flexibility. This makes it an ideal solution for detecting gases such as sulfur hexafluoride (SF₆), ammonia, and ethylene.
The LFD330C2 cooled LWIR infrared detector, with its high sensitivity, strong anti-interference ability and high spectral selectivity, has become an important technical means for SF₆/NH₃ gas leakage detection. It plays an irreplaceable role in ensuring industrial safety, protecting the environment and promoting the sustainable development of the industry in power, chemical, agricultural and cold chain fields.
