The HI70681L is highly effective effective cleaning and disinfection solution that is specially formulated for use in applications were a pH electrode can be coated with ink. Electrodes can become dirty from use and will produce inaccurate results even as they read correctly in a pH buffer. Hanna's cleaning solutions eliminate impurities and residues that are left on electrode surfaces when immersed in samples during measurement and 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 prevent any clogging of the junction. Hanna's line of cleaning solutions have been specially formulated to have an expiration of 5 years from the date of manufacture for an unopened bottle.
  • Specially formulated cleaning solution to remove ink stains from a pH electrode
  • Air tight bottle with tamper-proof seal to ensure quality
  • Expiration date and lot number clearly marked on the bottle
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.
