PH Sensor + Raspberry Pi

Hello, maybe someone has already tried using the PH Sensor on the IO Expansion HAT For Raspberry Pi (dfrobot.com/product-1930.html)

I was wondering if the Analog PH Sensor works well with this as this already have a ADC so that I won't be needing to buy a separate ADC, but I keep getting wrong readings using it. Tried calibrating it as well
