Use pH sonda without Module BNC

Using Arduino Sensors
1

Hi!!
My question is:
I can read any data just connecting the pH probe directly to the analog input of arduino?
The probe creates a potential difference ? (Voltage)..
Or should connect to a 5V supply ?

To simplify:

I can connect to the analog input,this?:

Sorry for my bad english.
Thanks!!

No.

You need a very special amplifier. There are a few DIY amplifier examples on the web, but they are not for beginners because of the extremely high impedance of a pH probe.

My question is if I get a potential difference at the output of the probe.
No external power ?
I know do an operational amplifier with high input impedance, but that was not my question.

The answer is NO.

Yes, that is how a pH electrode works. You can't measure the potential difference with an Arduino or a DVM, unless you use an amplifier.
