How does the tester work?

  • Connect the BNC connector of the electrode to the pH tester and remove the protective cap containing storage solution from the electrode
  • Rinse the electrode with running water and dry it using clean kitchen paper
  • Press the on/off button to turn on the tester
  • Place the electrode in the (soft) substrate (make sure the substrate is well wet/damp, otherwise the tester will not work properly) or liquid to be measured
  • Wait for the value to stabilise. The measurement is now complete
  • Press the HOLD button to save the measurement. Do not forget to press the HOLD button again when the tester is used once more
  • Rinse the electrode with clean water after use, so that no residue is left on the electrode. Replace the electrode in the protective cap containing the storage solution
  • Press the on/off button to turn off the tester


We recommend storing the tester with KCI storage solution in the protective cover.

Nice, Tough & Comfortable!
Size: 6.5 Wide Big Kid, Color: Black
Bought as an everyday school shoe for my 10 year old son. He likes them a lot and is holding up great through rough boy play, and they still look good after a couple months now.

Pink and purple perfection
Size: 13 Little Kid, Color: Pink/Purple, Size: 13 Little Kid, Color: Pink/Purple
Fits great and perfect colors for my (not so) little. This is her first pair of "tie" shoes so we're still learning, but the laces are a good length for teaching and practicing. She says they're very comfortable too.
