Want to measure pH directly? Use the Interactive Selection Tool to find the right sensor for your application.

  Calculate pH using either the concentration, weight, or volume method.

What is the implication of the pH measurement? This calculated value is fundamental in chemistry, because it has implications for industrial, pharmaceutical, and other commercial applications, such as food and wine. In addition, pH is a measurement of acidity or alkalinity, which can be useful for scientific and environmental applications. It is a fundamental parameter used to understand the properties of soil and water. pH is also closely observed in agriculture, horticulture, aquaponics, and aquaculture.
