Ph Meter And Its Applications

pH is the measure of the level of acidity or alkalinity of any liquid or solution

. A specific pH level is to be maintained in all the living organisms so as to sustain in this world. Even blood and water have their own pH values.

pH measurement should be done for all the processes which involve water or soluble compounds. It is done using an electronic instrument, a pH Meter which consists of 3 parts an electrode that is dipped in the solution to measure the voltage, a display, and a chip or sensor to process the pH value.

pH is the measurement of hydrogen ion concentration of a liquid, with values ranging from 0-14. These values indicate the level of acidity and alkalinity. Since pH value 7 is the center of the measurement scale, it is neither acidic nor basic and is, therefore, called neutral".

It is very important to understand the pH value of any substance, so that it can be put to effective use. If the pH value of a soil sample is found to be in an optimal range, it is considered to be the most suitable for cultivating wheat and other crops, thus maximizing the yields and returns from the soil. In some situations, the rainwaters pH was found closer to 0 than to 7. Thus, that sample was more acidic.

Maintaining perfect and accurate pH levels helps in several daily activities like keeping the milk from turning sour. Thus, a pH meter plays a significant role in everyday life, even though it is not explicitly used by a common man.

pH meters are employed profusely in other diverse fields like chemical industry, water purification processes like reverse osmosis, Hexavalent chromium destruction, electroplating, cyanide destruction, neutralization of effluent in steel, pulp and paper, pharmaceutical manufacturing, biotechnology and petrochemical industries etc. Hence, pH meter helps in analyzing the exact pH value of chemical substances and food grade products, thus ensuring high levels of safety and quality.

In India, there are several pH meter manufactures who deliver high performance and analytical microprocessor-based pH meters which use latest technology. Before purchasing a pH meter for laboratory or commercial purpose, make sure that you buy from a reputed brand which is reliable and meets world class standards. Most of the pH meters which are available in the market have a lesser response time as compared to the traditional pH meters and are light and ultra0-ortable.
