Cleaning Solution for Inorganic Substances (230 mL) - HI7074M
In stock
The HI7074M is a highly effective cleaning solution that is specially formulated for use in applications were a pH electrode can be coated with inorganic substances. 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.
- Specially formulated cleaning solution to remove proteins from a pH electrode
- Air tight seal to ensure quality and efficiency of cleaning solution
- 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.
The Cleaning Solution Series ensures maximum efficiency and accuracy of your sensors when used for it’s designated application. 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. The HI7074M is a cleaning solution specifically for applications that involve the measurement of pH in a solution containing inorganic substances.
