info on measuring pH in DI water

[DJ88]

Ohh Gotcha..

From the reading I have been doing and what Randy Holmes-Farley passed on there is such a low content of H+ Ions in DI water that you can't get a proper reading.

Distilled water may have an Ion level of log of 1 x 10^7. But I am speaking about De-Ionized water. Different creatures. It is for this reason the probe does not work. These Ions aren't at the levels required for the probe to get a reading. FYI The Ions it is reading are available Ions within the solution. The link I posted explains this. It is neat reading for those who don't know what pH is. The link is made specifically for measuring pH with meters. Tho not all the links and such work.

pH represents the 'activity' of hydrogen ions in a solution, at a given temperature. The term activity is used because pH reflects the amount of available hydrogen ions not the concentration of hydrogen ions.

Hopefully that clears up the difference in wordings the two of us were using.. [img]images/smiles/icon_biggrin.gif[/img] Same track but different translations.. [img]images/smiles/icon_wink.gif[/img]

I had left out some things as I had put the link for the detailed explanations. [img]images/smiles/icon_smile.gif[/img]
