JHLK100-HQ series High Precision Portable Mixed Gas Leak Detector
Using the principle of infrared spectroscopy (NDIR), the leaked SF6/CF4 and C4F7N gas concentrations can be quantitatively detected in real time
It is mainly used in SF6/CF4 and C4F7N mixed gas leakage detection of mixed gas equipment such as GIS in the power industry
