pH Measurement

pH Measurement

  • Cole-Parmer offers an extensive selection of pH meters, and pH instruments for testing and measuring pH

pH measurement is one of the most important measurements taken in science, industrial, and food processing applications. What is pH? In Chemistry, pH is the measurement of the acidity or basicity of an aqueous solution or food products. Pure water is considered neutral, with a pH value of 7.0. A pH value less than 7.0 is considered acidic and pH greater than 7.0 is considered basic or alkaline.

pH measurements have critical implications in a wide variety of applications and disciplines including biology, chemistry, food science, engineering, environmental testing, medicine, and much more.

Whether you are checking the pH of solutions and products in your biology or chemistry lab, or checking the pH values of lakes and streams, or you want to evaluate the pH levels of your household swimming pool or fish aquarium, our selection of pH meters, pH buffers, and pH testing accessories is among the best.
