JHLK100-HQ series High Precision Portable Mixed Gas Leak Detector

???

recommendation index：

Adopt high-performance imported infrared sensors

High detection sensitivity, up to 0.01 ppm

With zero calibration function and third-party calibration function

Sound and light alarm function, users can set the concentration alarm threshold

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
