When the detection pen 17 completes the detection, the solenoid valve 6 is closed and the second water pump is started at the same time. The sample water in the sampling area can be quickly extracted and discharged to the outside of the cylinder 1 through the second water pump and the liquid extraction tube 20, and then the first water pump 12 is started again.
