Electrical Characteristic Curve
The corresponding table of output voltage and concentration shows that the
higher the turbidity value is, the lower the output voltage is.
In the chart, many customers do not know how to convert the percent（%）to
turbidity units (NTU).
The following conversion formula is obtained after verification:
10-6 (PPM)=1ppm=1mg/L=0.13NTU (empirical formula)
that is: 3.5%=35000ppm=35000mg/L=4550NTU
