Hello everyone,

Could you possibly enlighten me which principle soil ph meters use?

I understand that they have an aluminum and copper electrodes. But I cannot find any information about this one (only the one with silver wire coated with AgCl)

Thanks in advance

 

It depends on your needs, but it is much less expensive to buy kits for testing pH than to buy a pH meter.

I'm not sure, but I think that they rely on the fact that the aluminium corrodes faster in more acidic  soils and thus sets free more electrons which pass through the meter and give a larger reading.

Or they may work on a  principle is similar to this.

How would that help find out how the meter works?

Geeze, I misread the post, I thought the question was which pH meter to use.

You can use the Takamurra DM15 soil pH meter
