The pH-sensitive glass membrane lets hydrogen ions to go through, generating a potential variation. This potential change is converted right into a pH examining via the meter.5 k?, it's strengths around ceramic junctions. The platinum junction is much more delicate to mechanical stress and can also be under optimum for strongly oxidizing or minimiz

As a result of sensitivity with the electrodes to contaminants, cleanliness in the probes is important for accuracy and precision. Probes are frequently stored moist when not in use which has a medium appropriate for The actual probe, which is typically an aqueous Alternative readily available from probe makers.[11][fifteen] Probe producers provide
