Turbidity is a measure of the cloudiness of water and is used as a key water quality indicator. This can then be used to quantify the amount of particles disrupting light passing through a liquid. For example, muddy water has a lot of small soil particles. This disrupts light going through it and makes it very cloudy and turbid. However spring water tends not to have many particles in and so is...
Turbidity measures the cloudiness/haziness of a fluid. It is a key test for water quality, turbidity is caused by particles of varying size scattering/absorbing the light and creating a cloudy appearance. The turbidity of a sample will increase with the amount of undissolved solids present.

Turbidity meters are used to quickly measure the turbidity (or cloudiness) of water, caused by suspended solid particles.
Understanding how turbidity meters work can help in achieving more accurate results and ensuring the samples and meter are handled correctly.

Q: I am looking for a new benchtop turbidity meter, but Hach offer two versions - the TL23 series and the TU5 series.
Which turbidity meter should I choose?
What is the difference between the TU5 and TL23 models?
A:Â There are many differences between the two ranges, as explored below;
Overview
TL23 Series - for a wider range of applications, a lower cost option using traditio...
The popular 2100N and 2100AN series of turbidimeters (turbidity meters) are being phased out and discontinued.
They are replaced by the new TL23 series which offers some great additional features - we've taken a look at what the TL23 series offers over the 2100 series.
