A twin needle Kelvin probe. Quick ,low cost and minimal effort to make.

An improved version of my previous Kelvin four-wire probes.
It will completely eliminate the test lead and needle resistances.
Only requires a needle, heat-shrink sleeving and wire, and a few minutes of your time!
See the prevoius videos about the low cost milliohm tester and Kelvin probes.

I'm glad you liked it!

[@wendellwagner500]

neat, cheap and quick...thanks

[@das250250]

Nice , I think you can buy dual needles but it seems your idea will probably work a treat . Did you test it against your first attempt ?

[@space_cowboy007]

so if i followed all your videos correctly the "best" design is this but with the wires soldered in the needle's eye, yes?

[@richardlangner]

Yes of course you are right. My later versions used the eyes. Same applies to my kelvin probes ruclips.net/video/oAgExeQzwdEr/видео.html
