Welcome to Camlab's comprehensive list of blogs on the subject of turbidity and water analysis. As a leading provider of laboratory supplies, we understand the importance of accurate and reliable water analysis, especially when it comes to drinking water. We have curated a selection of informative and insightful blogs from experts in the field, covering topics such as the latest turbidity measurement techniques, regulatory updates, and case studies of successful turbidity management. Explore our collection and gain valuable knowledge on this critical area of water analysis.
Turbidity is a measurement of suspended particles in water that scatter or absorb light. For example, the more suspended solids there are, the murkier the water will appear and the higher the turbidity is. Turbidity will also depend on the size of the particles, as this will affect the scattering or absorption of light.

Why measure turbidity?

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.

For an accurate measurement of turbidity a sample vial is placed in an nephelometer meter called a turbidimeter or turbidity meter. The meter emits a known intensity of light through the sample cell and the scattered light is measured at 90 degrees to the light source to give a turbidity reading in units NTU (nephelometric turbidity units) or FTU (formazin turbidity units). There are a range...
Q: Our turbidity meter comes supplied with a bottle of silicone oil. What is this for? Why is it important in the test?

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...
Ingredients in beer can precipitate forming a hazy or milky appearance which can affect the end product quality. Proteins, carbohydrates, polyphenols, fatty acids, nucleic acids amino acids, etc. present in the beer whilst at room temperature may be clear, when chilled reacts and clump into larger particles known as haze. These particles are large enough to reflect light and the turbidity can b...
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.
