| Project Background

The pH value of purified water is a key physicochemical indicator for assessing its acidity or alkalinity. In industries such as pharmaceuticals, biotechnology, laboratories, and electronics, the chemical stability of water is of paramount importance. Measuring pH effectively evaluates the corrosive tendency of water toward pipelines and equipment, while also ensuring that contact with production processes, formulations, or precision instruments does not trigger unintended chemical reactions or compromise product stability.

| Project Overview

In this test, a benchtop pH meter was used to analyze the pH value of purified water samples. The working principle of the pH meter is based on the Nernst equation and the response theory of the glass electrode. By measuring the potential difference between the indicator electrode and the reference electrode immersed in the aqueous solution, and converting it into the corresponding hydrogen ion activity index (pH value), it directly reflects the acidity or alkalinity of the water sample.
