Could you attach a photo about your hardware connection?
It is better to change another Analog pin, and try again. Because 17.3 convert to voltage is almost close to 5V. So your analog pin has been set high.

sorry if I put the time I take care of a lot of things

First of all ph meter is supplying 5VDC

but when I connect the two pins I always show 17.3 ...

Could you use a cable to connect two BNC pins together?
The PH value will be 7 at that time.

And please check the voltage. it needs very accurate 5V power supply.
