The 2020 turbidity tubes are optically selected but very small variations in thetubes may cause different readings on the same sample in low turbidity water. Ifgreater accuracy is required, such as for Drinking Water requirements, the tubessupplied with the 2020 should be individually calibrated. This procedure isimportant for reading below 10 NTU but is probably not needed for samplesabove 10 NTU.14
