[0030] In summary: the utility model discloses a methane meter suitable for low temperature and high humidity working conditions. The methane meter in this utility model is a mature existing technology on the market. The utility model can be used as a reference. The model is VOCs-800P and the brand is Tianrui Instrument. There are specific physical pictures, and it is a portable instrument for volatile organic compound analysis; the traditional methane composition measuring instrument is provided with a digital display screen 11 in front, which is used to display and record the measured methane concentration data. If the methane measuring instrument body 1 is not used for a long time, the user can reversely rotate the knob 35, and the knob 35 drives the threaded rod 36 to rotate, and the threaded rod 36 will drive the bearing 37 and the protective slide plate 32 to slide vertically downward along one side of the sliding chamber 34 until the protective slide plate 32 slides along the sliding chamber 34 to cover the front side of the digital display screen 11. This operation is blocked by the protective slide plate 32 on the front side of the digital display screen 11. The digital display screen 11 is dustproof and protected to prevent external environmental factors from damaging the digital display screen 11. If the digital display screen 11 needs to be used, the user can turn the knob 35 in the forward direction, and the knob 35 causes the threaded rod 36 to rotate in the forward direction. The threaded rod 36 drives the bearing 37 and the protective slide plate 32 to move vertically upward along the sliding chamber 34 until the protective slide plate 32 is retracted into the top inner cavity of the protective chamber box 31. After the protective slide plate 32 is removed, the opening 33 is reopened.
