The LK302 Extra High Sensitivity SF6 Leakmeter is a highly accurate, reliable and stable quantitative gas monitoring system. The applied technology is based on of photo-acoustic infrared spectroscopy. This physical and non-destructive working principle implies that the LK302 Extra High Sensitivity SF6 Leakmeter -compared to other detectors- achieves highest accuracy due to the integrated temperature and pressure compensation while measuring LK302 Extra High Sensitivity SF6 Leakmeter down to 5ppbv. Water vapor interference can be excluded through the installed acquisition and crosscompensation of the moisture content while customers can choose for compensations of further VOCs being present that might interfere the measurement’s preciseness. The reliability and accuracy of measurement results is ensured by regular self tests of the system. Due to the physical working principle the LK302 Extra High Sensitivity SF6 Leakmeter requires no consumables and beyond that very low maintenance. Re-calibration is recommended once a year and can be executed by the operator.
