Fiber sensor directly detects water molecule content in SF6 gas with absolute error of PPM≤±2ppm. Within dew point value scope of SF6 at application site, it provides better dew point precision. Its precision is ±1℃ at -60℃ , ±5℃ at -50℃ , ±0.3℃ at -45℃ and ±0.1℃ at -40℃ , which fully meet precision requirement of onsite detection.
The use of infrared absorption spectrometry for detection, anti-interference ability, 'a scanning-based micro-water detection system' has a utility model patents (Patent No .: ZL 2011 2 007 4340.0).
Completely independent development, with independent property rights and related patents.
Compact structure, small size, easy to carry.
Seven-inch high-definition LCD touch screen, touch operation, simple and intuitive.
Using high-capacity lithium battery, suitable for field operations.
Instruments imported gas components, sealing performance is good, no SF6 gas leak detection process.
