High-precision red phosphorus content measuring device

The utility model relates to the technical field of red phosphorus content determination, in particular to a high-precision red phosphorus content determination device which comprises a determination device body, a red phosphorus content determination cavity and a control cavity are sequentially arranged in the determination device body from left to right, and an electric lifting rod is mounted at the bottom end of the inner wall of the red phosphorus content determination cavity. A lifting frame is mounted at the top of the electric lifting rod, a detection vessel is clamped at the top of the lifting frame, a turning cover is mounted at the top of the measuring device main body and close to one side of the red phosphorus content measuring cavity, and a gas chromatography detector is mounted at the bottom end of the turning cover in an embedded manner. The device has the advantages that the determination position of the detection vessel for bearing to-be-detected red phosphorus is conveniently adjusted, the d
