Inductor meter

Can anyone help me with a simple circut for measuring inductance. I need to make a couple inductor for electrolysis cell and create resonance between the cell and the inductors and 42.8 Khz. And the reason I want to build it is I don't want to spend $50 on a meter I will only use once.
Thanks in advance

You shouldn't need an inductance meter.

What inductance do you require?

Just look up the formula on Google and wind it to the inductance you require. At that frequency it probably needs to have an ferrite core but you can get these from most electronic component distributers.
