LaMotte 2020 - Turbidity Tubes (Cont.); The 2020 turbidity tubes are optically...; 1. Fill each tube (0286)...; 2. Record a turbidity reading...

The 2020 turbidity tubes are optically selected but very small variations in the
tubes may cause different readings on the same sample in low turbidity water. If
greater accuracy is required, such as for Drinking Water requirements, the tubes
supplied with the 2020 should be individually calibrated. This procedure is
important for reading below 10 NTU but is probably not needed for samples
above 10 NTU.
