Portable infrared gas detector is a hand-held SF6 (sulfur hexafluoride) Gas detector for continuous measurement of gas. Adopted with imported gas infrared sensor, it utilizes unique method of data processing. Light emitting organic matter OLED screen, gives clear display in absence of light and when operated during dark. With Non-dispersive infrared (NDIR) principle, the detection resolution of leakage can reach up to 0.1ppm.
