Pool Line General Purpose Cleaning Solution (500 mL) - HI70614L


SKU: HI70614L Categories , , ,

In stock

HI70614L Pool Line General Purpose Cleaning Solution is a highly effective solution that is formulated for cleaning pH and ORP probes. Electrodes can become coated with a variety of substances when used in swimming pools, hot tubs, and spas. If the probes are not cleaned then inaccurate results can occur. Hanna’s cleaning solutions eliminate impurities and residues that are left on electrode surfaces. Hanna suggests cleaning the pH and ORP probes on a regular basis to ensure that the sensor is always clean and the junction free flowing.

  • Specially formulated for cleaning pH and ORP electrodes
  • Clearly marked expiration date and lot number for traceability
  • Air-tight seal to ensure the quality of the solution


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. The pH meters on the market today will allow an offset voltage (pH 7.01) 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 then any changes to the probe will result in inaccurate readings.

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. By simply immersing the electrode in the HI70614L cleaning solution for 15 to 20 minutes will dissolve any mineral deposits or other coatings.

After any cleaning procedure is performed it is important to rehydrate the glass of a pH electrode by placing in storage solution for 15 minutes. After the probe is rehydrated then a calibration must be performed. This is very important for process probes since many are used to monitor and control the dosing of chemicals. It is critical that the probe is clean and calibrated in order for a meter to maintain the ideal set point. The cleaning of pH and ORP process probes should be part of a routine maintenance program.
