[0040] The detector body 2 of this embodiment is a circuit board, and the shell 1 is made of a transparent material, so that the various components inside the shell 1 and the water sample entering the measuring chamber 8 can be observed. The power supply 3, the display screen 4, the control button 5, the signal transmitter 6 and the processing module 7 are all installed in the detector body 2, and the measuring chamber 8, the light source 9, the light receiver 10, and the detection sensor assembly 11 are all arranged inside the measuring chamber 8;

[0041] Power is supplied to each component by the power supply 3, and the light source 9 is used to generate light of a specific wavelength so as to perform optical detection by the light receiver 10; the light receiver 10 receives the reflected or transmitted light emitted by the light source 9 after passing through the water sample, and converts the optical signal into an electrical signal for analysis and processing by the existing program pre-examined in the processing module 7; the processing module 7 transmits the processed parameters to the control terminal through the signal transmitter 6 for further analysis and recording, so as to realize automatic recording of multiple water quality test results and upload the results to the control terminal, which can improve the accuracy of the test result recording, and at the same time can reduce the workload of the measurement personnel and improve the work efficiency.

[0042] At the same time, the display screen 4 can be used to display the water quality test results, operation interface and instrument status information after processing by the processing module 7; and the control button 5 can be used to control the switch of the instrument, set test parameters, start and stop the test process, and browse and select menu items.

[0043] The water sample is added into the measuring chamber 8 through the water inlet. After the water sample is added, the water inlet is sealed by the sealing member 12 to prevent leakage of the water sample.

[0044] Optionally, the processing module 7 of this embodiment can also be provided with a data storage device to store the detection data, support data export and transmission, facilitate subsequent data analysis and processing, and cope with and control the situation where the terminal is disconnected, and further ensure the stability of the data collection of the portable water quality detector.
