New Good Low Cost Inductor
« on: June 20, 2010, 01:23:35 pm »
I have a growing need to measure inductance.  It's time to pick up a meter.  There are tons in the $25 region from Hong Kong in E-Bay.  The US choices start at around $150.

Brands/Models/Vendor recommendations most welcome.

Thanks!!
Randy

Inexpensive meters measure at very low current and unknown frequency. This can give very misleading results.  Check this out:

Also search the Forum or Google (I think Steve Bench) for quality devices you can build, if you want.
