Product Overview

HI700601P is a general purpose cleaning solution that can be used in a variety of applications. Electrodes may become dirty during use, which can produce inaccurate results even if readings are correct in pH buffers. Hanna's cleaning solutions eliminate impurities and residues left on the electrode surface during measurement or when immersed in samples or stored improperly. Hanna recommends regular cleaning of the electrode bulb and junction to ensure the probe is always clean and to prevent junction clogging.

The most common cause of inaccurate pH measurement is a dirty or improperly cleaned electrode. This is very important because during calibration, the instrument assumes that the electrode is clean, and the standardization curve created during calibration will remain a valid reference until the next calibration. pH meters currently on the market will allow an offset voltage of approximately ±60 mV. Deviations from 0 mV are not uncommon, but ideally should not be greater than ±30 mV. The calibration process compensates for changes in offset voltage. If the mV offset continues to drift, and a dirty electrode is used to calibrate the meter, it will result in inaccurate readings.

Cleaning is a quick and effective procedure that should be performed regularly as a preventive measure against using a dirty electrode and to ensure that the junction does not become clogged. By simply soaking the electrode in HI70061P cleaning solution for 15 to 20 minutes, any mineral deposits or other coatings will be dissolved.
