Understanding the Importance of pH Measurement in Laboratory Settings with Ohaus pH Meters
In laboratory settings, pH measurement plays a crucial role in various scientific experiments and analyses. pH is a measure of the acidity or alkalinity of a solution, with a scale ranging from 0 to 14. A pH of 7 is considered neutral, while values below 7 indicate acidity and values above 7 indicate alkalinity. Accurate pH measurement is essential in fields such as chemistry, biology, environmental science, and food science, among others.
One of the key tools used for pH measurement in laboratories is the ph meter.
