Good evening.

I have just bought a pH/Redox meter. Everybody knows the basic principles for the measurement of protons concentration and the use of standard buffer solutions. It's easy to read a pH value and see that a solution is acid or basic.

On the contrary, whilst I know what a reduction potential is, I've never used a Redox-meter and I don't know what solutions I could compare and make a calibration. I've never found a chemistry book describing and giving the fundamentals of the routine use of a Redox-meter.

Do you know of a link to that subject or the title of a book ?

Thank you.

A redoxmeter is nothing else as a voltmeter which has a high ohm inlet. So there is no calibration. With an redox electrode you can measure potentials of chemical reactions.
