Calibration Fluids for pH and EC Meters

Calibration fluids are an important part of pH and EC meter maintenance. They are buffer solutions with a precisely defined value that are used to adjust and verify the accuracy of the meters.

In this category you will find various pH and conductivity calibration solutions, as well as liquids for cleaning and storing electrodes. The most commonly used calibration buffer solutions are pH 4.01, pH 7.00 and pH 10.01, which allow for two-point or three-point calibration of pH meters.

Proper calibration is important because electrodes gradually change their characteristics over time and can give inaccurate measurements without regular adjustment. Using quality calibration fluids and storage solutions helps maintain measurement accuracy and extend the life of pH probes and EC sensors.
