The camera is highly sensitive due to the sensitivity of Cooled QWIP detector when its temperature resolution reaches 0.025&C and leak detection sensitivity reached 0.0001 ml/s. A small temperature difference, the tiny leakage both can be detected and captured, so it

SF6 gas leakage infrared leak detector has a significant development to detect and identify the minimum leakage of SF6 gas equipment indoor and outdoor. For its different video alarm levels, it is the best tool to reduce environmental pollution and SF6 gas leakage.

Oct 07, 2010The photoacoustic gas analyzer SF6 LaserGasTest (short: LGT) is a portable gas detection system Made in Germany“ for fast and precise leak detection of the insulating gas SF6 (Sulfur Hexafluoride). By combining l aser source and photoacoustic spectroscopy (PAS), a significantly higher SF6 selectivity to comparable detectors can be achieved. To be more specific, LGT can detect the presence of about 10 ppb of SF6, which is equivalent to the detection of one SF6
