A pH meter. A pH Meter is a device used for potentiometrically measuring the pH, which is either the concentration or the activity of hydrogen ions, of an aqueous solution. It usually has a glass electrode plus a calomel reference electrode, or a combination electrode.
To use the visual method is simple. A pH sensitive indicator is placed in the measured solution and the indicator will change color depending on the pH level. To get the pH value, compare the color to the pH chart that comes with the indicator.The accuracy of this method is, for obvious reasons, low. However, it can be used for a rough estimation of the pH level. The pH indicator can either be a chemical indicator or a special pH paper, so-called pH testing strips.etermine the pH level. A common method to measure the pH level is to use a pH indicator and the related pH color chart. There are several methods to measure pH. However, the two most common methods are the indicator, or visual method, and the potentiometric method.
