Which device is commonly used to measure the pH level of liquids in a business setting?

In most businesses, a pH meter is the standard tool for measuring liquid acidity. It works by comparing the liquid’s electrical potential to a calibrated reference electrode, giving a direct pH reading. The meter’s probe is dipped into the liquid, and the device displays the pH on a digital screen after a few seconds. For example, a brewery uses a pH meter to check the acidity of wort before fermentation. This method is quick, accurate, and widely accepted in industrial quality control.
