TDs and pH testing is very essential when it comes to the quality of water.TDS stands for Total Dissolved Solids. These solids include the total amount of mineral salts, metals or mobile charged ions that could be dissolved in water's volume. The TDS meter indicates the concentration of dissolved solid particles in the water by measuring the electric conductivity of the water with a TDS meter which converts the electrical conductivity reading to represent the total dissolved solids in the water

 Dissolved ionized solids like salts and minerals increase the electrical conductivity of a solution which can be used to estimate the dissolved particles in a solution. However, sugar and other microscopic solid particles like colloids which are organic solids that dissolve do not significantly affect the conductivity of a solution. Therefore, the most accurate way to measure TDS of water in a laboratory is to evaporate the water leaving behind dissolved solutes as residue and then weighing the residue. Nevertheless, the process of evaporating this water and weighing what's left may not be easy for an average person.


The best tds meters  on the other hand is a scientific instrument that measures the level of hydrogen-ion activity in water based solutions indicating its alkanity and acidity. It works by measuring the difference in electrical potential between a pH electrode and a reference electrode and hence sometimes its being referred to as potentiometric pH meter. The difference in electrical potential relates to the acidity or the pH of the solution.


The results of the of chemical reactions taking place in water often depends on the acidity of the water and hence its useful to know the acidity of the water using the pH meter. The knowledge of the pH meter system is helpful in many fields like in agriculture for soil measurement, laboratory chemical analysis, water quality for municipal water supplies, brewing of wine or beer, manufacturing healthcare and clinical applications like blood chemistry, also use in environmental remediation and many other applications.


There are many types of pH meters ranging from simple and inexpensive pen-like devices to expensive and complex with computer interfaces and several other inputs for indicator. The output can be battery powered or depend on line power. Some versions also use telemetry to connect the electrodes to the voltmeter display


Finally, the pH and TDS meters are advantageous tools for measuring the purity of the water. The lower the amount of total dissolved solids the purer it is and safer to drink. On the other hand, its ideal for your health and any water basin to have a pH of seven. For more information about alkaline water, go to
