Methods used to retrieve these WQP measurements are dependent on the optical properties of the inland water bodies. While TSS is an optically active parameter, TDS is optically inactive with a low signal鈥搉oise ratio. The detection of TDS in the visible, near-infrared, and infrared ...
Knowing the amount of total dissolved solids (TDS) in water is one of the important requirements that helps determine the efficiency of a particular water treatment device in removing bacteria or unwanted elements in the water. What is TDS? How is it measured? Why is TDS measurement important?
Depth of water is measured by a non-vented strain gauge. Depth is calculated from the pressure exerted by the water column minus atmospheric pressure.
Electrical conductivity is an indicator of water quality. Conductivity data can determine concentration of solutions, detect contaminants and determine the purity of water.

When it comes to determining water quality as part of your application or process, pH and Oxidation Reduction Potential (ORP) are among the most critical and insightful measurements. From simple end-point values through continuous readings in the harshest, most strictly regulated e...
Until the chemical mechanism of the interference is quantitatively understood, dilution with deionized water appears to be the best approach to obtaining reliable data. This may limit the technique's usage in waters of high TDS, and low reactive silicate. 展开 ...
