From laboratories and quality control to schools, pH meters have a wide range of application. They are often used in solutions to indicate alkalinity or acidity, some also measure electrical potential, these are called "potentiometric pH meters". Usually with a meter and a probe, some pH meters also measure temperature. Whatever type of measurement is needed RS offers a wide range of pH meters to meet your pH measurement needs.

The HI1270 (RS article 214-849) is the replacement pH electrode.
