What is the minimum level of filling solution to use in a refillable pH electrode?
The filling solution level must be higher than the sample level to maintain a uniform flow of filling solution. A level of at least 2cm above sample height is recommended. Virtually everyone who measures pH encounters problems with their electrodes at some stage. Reagecon have issued a Technical Paper on this subjecting, including: • Full details of how to identify and rectify electrode faults. • Preventative maintenance required to ensure accurate result and electrode longevity • The importance of correct storage, handling and a routine cleaning routine.
