What does a pH meter measure?

An electronic BOQU pH meter is used to obtain more accurate pH measurements. A pH meter is an instrument used to measure hydrogen ion activity in solutions - in other words, this instrument measures acidity/alkalinity of a solution. The degree of hydrogen ion activity is ultimately expressed as pH level, which generally ranges from 1 to 14.

This pH measurement is directly related to the ratio of hydrogen ion concentration and hydroxyl ion concentration ([H+] and [OH-], respectively). The general breakdown of pH levels is listed below:

Neutral solution: pH = 7

Acidic solution: pH < 7

Basic solution: pH > 7

A neutral solution will show a pH of 7 due to the equal activities of hydrogen and hydroxide ions. Acidic solutions exhibit pH readings below 7 (higher hydrogen ion activity compared to hydroxide ion activity), and basic (or alkaline) solutions exhibit pH levels above 7 (hydroxide ion activity is greater than that of hydrogen ion).

 

Applications

pH meters are widely used in the following industries: Applications

Food & beverage pH measurement

Pharmaceutical pH monitoring

Oil & gas pH online pH measurement

Agriculture pH monitoring

Water treatment plant pH measurement

While this is not an exhaustive list of industries utilizing pH meters, it is clear that pH meter is an essential component of science and that it has a big impact on our lives. For example, they can be used to measure acidity levels in wastewater, which is a vital component of the wastewater treatment process. They are used to analyze the exact pH value of food-grade products and chemical products to ensure safety and quality, or they can be used to evaluate the acidity/alkalinity of drugs in the pharmaceutical and biotechnology industries.
