The KDZD-SF6 is a portable SF6 quantitative leak detector based on infrared spectral absorption (NDIR) technology. It features a 4.3-inch TFT touchscreen and a 32-bit ARM microcontroller for high-precision data sampling and analysis. With dual-wavelength temperature compensation, it delivers reliable measurements across a range of 0~999.9PPM, even at ultra-low concentrations (0.01PPM resolution). The infrared sensor offers a 10-year lifespan, no cross-interference with other gases, and low maintenance costs. It supports both digital and analog output, with a built-in rechargeable battery for field use, making it ideal for SF6 gas leak detection in power systems.
