If the current signal (converted into voltage) output by the UVC sensor is higher than a set range, reducing the current of the UVC-LED lamp until the output current (converted into voltage signal) of the UVC sensor is in the set range; if the current signal (converted into voltage) output by the UVC sensor is lower than a set range, increasing the current of the UVC-LED lamp until the output current (converted into voltage) of the UVC sensor is in the set range; if the output current (converted into voltage) of the UVC sensor is in a set range, recording the input current (input reference current) of the UVC-LED lamp and the output current (output reference current) of the UVC sensor at the moment, and converting the input current into (reference voltage).

The transparent water chamber 21 is filled with the tested liquid to be tested; the UVC-LED lamp tests an output current of the UVC sensor (converted into a voltage) by a reference current, and then calculates an absorption coefficient of the measured water sample using an α formula shown in fig. 6 from a current value output from the UVC sensor and the reference current value.
