专注于SF6气体检测的专业化
What are the SF6 leak monitoring and alarm systems, and what are the differences?
At present, the application of SF6 leak monitoring and alarm system in the market is divided into qualitative detection and quantitative detection. Qualitative generally adopts thermal cracking and laser technology, qualitative testing products have high stability and high detection accuracy, which can meet most customer needs; The quantitative detection products use the principle of infrared spectroscopy, that is, the principle of infrared laser, its detection accuracy is high, up to 1ppm, but the stability is not qualitative high, because SF6 gas has a very strong absorption characteristics of specific bands of infrared light, high sensitivity, not affected by the environment and interference, no other gas interference. At the same time, the detection error caused by the change of ambient temperature and humidity is small.
