The electrodes become dirty with use and produce inaccurate results even if they are read correctly in a pH buffer. Hanna's cleaning solutions remove impurities and debris that remain on the electrode surfaces when immersed in samples during measurement or if improperly stored. At Hanna, we recommend regularly cleaning the bulb and electrode junction in our ready-to-use cleaning solutions to ensure the probe is always clean and to prevent any junction obstruction. All cleaning solutions are packaged in an airtight bottle with a tamper evident seal to ensure quality and freshness. All solutions show a lot number and an expiration date.
