The conductivity probe is supposed to include three ranges of low (such as 0.1-199.9 uS), medium (such as 0.2-1.999 mS) and high (such as 2-19.99 mS), namely, a detector can select different power amplification times according to the magnitude of the conductivity digital signal of the detected water body. After the conductivity digital signal of the detected water body is checked on a computer, when the detected water body is determined to be low-concentration conductivity (assuming that the conductivity of the detected water body is 178.6uS), small power amplification times are adopted, namely, a low range is selected for measurement; and when the high-concentration conductivity (the assumption shows that the conductivity of the detected water body is 15.2mS), the high power amplification factor is adopted, namely, the high range is selected for measurement, so that the high-accuracy measurement of the conductivity of the water body to be detected is realized.
