- Cleaning is a fast and effective routine which should be performed on a regular basis as a preventative measure against using dirty equipment.
- Always clean the junction and bulb of the electrode
- Always clean your meter, electrode or probe before calibration
- The most common cause for pH measurement inaccuracies is an unclean or improperly cleaned electrode. This is very important to note, because during calibration, modern pH meters assume that the electrode is clean and will give you a starting point accordingly. So, if you haven’t cleaned your meter, your readings will be inaccurate from the start.
The single dose sachets are really handy with each sealed sachet holding just the right amount of solution. Each time a meter or electrode is cleaned using the Hanna sachets, it is like using a newly opened bottle of solution!
Electrodes become dirty from use and will produce inaccurate results even if they read correctly in a pH buffer. Hanna’s cleaning solutions eliminate impurities and residues which are left on electrode surfaces when immersed in samples during measurement or when stored incorrectly.
At Hanna, we suggest cleaning the bulb and junction of your electrode on a regular basis in our ready-to-use cleaning solutions to ensure that the probe is always clean and to prevent any clogging of the junction.
All cleaning solutions are packaged in an air tight sachet to ensure quality and freshness. All solutions show a batch number and expiry date.
