How does the conductimeter measure conductivity? i think that it cannot be measured?
does it really measure conductivity or somethin else that can be related to conductivity?

Dear ahmedezat,
I’m really assured that you know; Conductivity needs a current to be measured,
so you may got problems with electrolysis and polarisation potential, I think.
To avoid this “unlike”, misleading effects the industry uses “alternate current”
of low frequency (Common 50 Hz or 100Hz OR 60Hz or 120Hz; Why?).
For more comparable measurements often 500Hz has been “standardised”.
But keep care, it’s a method, which is influenced by several parameters, like
Temperature, Water-quality, and of course Frequency (Why again?), ?etc.?.
Don’t forget the blank, it’s a method it depends very strong on!
Question: By what concentration is the Conductivity a maximum?
Good Luck!

I think by high concentration of minerals in water am i right?

Dear ahmedezat,
I would have to say: YES, ? But ONLY in case IF I prefer to be satisfied with HALF
of the answer.
A Maximum, of course a Minimum too, must have a “LEFT side” AND a “Right side”, too!!
You can do it easier, if you start your answer for this Type of Questions like:
“The mobility of humans is increasing with “building more cars”, TILL …… becomes more
important , which lowers the human mobility again.”
Of course any similar recipe will do it, too!
Good Luck!
