Thanks very much for the reply and the help advice. Where would I be able to buy the moving coil meter? If I go to an electronic shop and ask for a moving coil meter would they give me one?

Don't laugh but HF sells both a PH meter and a soil moisture meter for $5 each! And believe it or not they work fairly well... not like a professional, complex meter, but for relative indications they work good. No electronics inside, just bi-metal that generates a small current to deflect a calibrated meter. These are very rudimentary devices but if all you need is a relative indication they work fine.
Radio Shack used to sell a cheap multimeter with moving coil meter, but they are probably all digital now. You can use a digital meter with a current scale instead of the moving coil meter.
