Maintenance Solutions

Maintenance solutions are very easily overlooked but they are an important of the measuring system. Maintenance solutions include both storage and cleaning solutions.

Storage Solutions

The sensitive pH glass must be hydrated for an accurate measurement. A hydration layer can take hours to completely form. The junction of the reference cell also needs to be hydrated so that ions can move freely from the inside of the cell to the outside. Storage solutions are manufactured to be able to maintain the hydration for the probe while minimizing changes to the reference cell composition.

Cleaning Solutions

The sensitive pH glass must be clean for an accurate measurement. A build up on the glass will change the measured potential in the solution. This build up can be hard to discern with the naked eye but has an impact on the measurement. If a probe is calibrated when there is a coating and the coating changes in the solution then the calibration is no longer valid and measurements not accurate. It is important to have a regimen to periodically clean the pH electrode to maintain it in the optimal condition. We offer a variety of solutions including general purpose and ones specific to the application. Solutions are available in bottles and single use sachets.
