    Embedded SF6 sensor is an infrared gas sensor based on single light source and dual beam non-color infrared measurement technology (NDIR)


    Designed for SF6 pumping leakage design. The advanced infrared sensor has good linearity, repeatability and solid air chamber to ensure long-term stable and reliable measurement.


    The pipeline SF6 sensor has strong selectivity to gas, and is not interfered by H2O, ethanol, CO2 and other gases. The sensor uses imported high-precision infrared emission detectors and industrial-grade high-stability single-chip microcomputers, with other gas interference, long-term stability, long life, and high precision.
