    HI GroLine General Purpose Cleaning Solution Sachets 20 mL (25 Pack)

    HI70061G is a GroLine general purpose cleaning solution that can be used for several applications. Electrodes become dirty with use and generate inaccurate results even as they read correctly in a pH buffer. Cleaning is a fast and effective routine that should be performed on a regular basis as a preventative measure against using a dirty electrode and to ensure that the junction is not clogged. Hanna’s cleaning solutions eliminate impurities and residues left on electrode surfaces from sample measurement or incorrect storage.

    The most common cause for pH measurement inaccuracies is an unclean or improperly cleaned electrode. During calibration, the instrument assumes that the electrode is clean and that the standardization curve created during the calibration process will remain a valid reference until the next calibration. The calibration process compensates for the change in offset voltage. If the mV offset continues to deviate and the meter is calibrated with a dirty electrode then inaccurate readings will result.  Immersing the electrode in the HI70061G cleaning solution for 15 to 20 minutes will dissolve any mineral deposits or other coatings.
