Hanna Instruments GroLine Cleaning Solution

Starting At: $33.50

SKU: TST-HI-70061G-B

The GroLine Cleaning Solution is specially formulated for cleaning GroLine pH electrodes. Keeping pH electrodes clean is imperative for accurate readings, as particles can containment the sensor tip which can affect the calibration process. Hanna Instruments provides a fast and effective solution to this issue, simply immerse the electrode in the cleaning solution for 15-20 minutes to dissolve any contaminated particles. The Cleaning Solution works best when integrated with a regular cleaning routine.

GroLine General Purpose Cleaning Solution

Hanna’s cleaning solutions eliminate impurities and residues that are left on electrode surfaces when immersed in samples during measurement or when stored incorrectly. Hanna suggests cleaning the bulb and junction of your electrode on a regular basis to ensure that the probe is always clean and to prevent any clogging of the junction.

The most common cause for pH measurement inaccuracies is an unclean or improperly cleaned electrode. This is very important to note because, 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. pH meters on the market today will allow an offset voltage of approximately ±60 mV. The deviation from 0 mV is not unusual but ideally should be no greater than ±30 mV. 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.

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. Simply immersing the electrode in the HI70061G cleaning solution for 15 to 20 minutes will dissolve any mineral deposits or other coatings.
