insulating gas LaserGasTest™ – HLS Hypertech Laser Systems

Oct 07, 2010 · The photoacoustic gas analyzer insulating gas LaserGasTest (short: LGT) is a portable gas detection system "Made in Germany“ for fast and precise leak detection of the insulating gas gaz sf6 (Sulfur Hexafluoride). By combining l aser source and photoacoustic spectroscopy (PAS), a significantly higher sf 6 selectivity to comparable detectors can be achieved. To be more specific, LGT can detect the presence of about 10 ppb of Sulfr hexafluoride, which is equivalent to the detection of one Sulfr hexafluoride molecule in one hundredGet price
