In the adjacent video ZP shows you how to measure the pH of milk and orange juice using GFET and a ZP pH sensor, but before you start to work on your application please start by following the advice on this page. 

Before working on your own application you need to get a  good first test under your belt and so this page is intended to get you there.


The adjacent data was gathered by a ZP engineer in his kitchen so you don't need a lab but you will need the following items::

  • ZP's GFET
  • ZP's pH sensors
  • ZP's pH test solution
  • ZP's pH cable (ZP4000441).

We link to these items in the button below.


Do know that ZP does want you to have a great starting experience so please feel free to reach out to us at ZP.    2022
