asking about components

[Gendiaaa]

This ph meter module i fond someone share it but i do not understand what is pg item is the component that labeled 073100015 and also jp1 i think JP1 refers to jumper wires ?

AS it says: PG is the BNC probe input or PluG.
JP is a JumPer. Not a wire but a pluggable one.

Thank you very much but i do not know why he made this line jp1 looks like if its connected it will by-pass the BNC plug .. do you sir know why this line needed for ?

Hello,

It could well be that JP1 is only used for testing the Vguard voltage.
In normal operation JP1 should be open.

you can pass current through a liquid, get the amps, and its like ph, its how conductive the water is, but how do you go from that to an electronic ph metre? what more is there to it, I cant really gather it from looking at the circuit by itself...

Try this explanation.

I see so its not the current, its the difference in voltages!!! so if i get a wire, from one solution to another, itll actually generate a tiny bit of current like how a hall sensor generates its tiny voltage?
