edit: putting this at the top because people keep answering questions I didn't ask:
Where can I get this done cheaply by a place that is hobbyist friendly? I don't even know where to look.
I imagine there are plenty of labs that do this kind of thing, but any that I can find via google do not disclose pricing and seem geared exclusively towards volume / B2B and are not hobbyist friendly.
Are there any cheap-ish labs that are friendly to the hobbyist where I could send my precision resistors to find out their true value down to the PPM range or better? PPB would be ideal. I'm using these to calibrate my 5.5 and 6.5 digit multimeters.
Bonus question: I'm interested in getting a calibration report on my precision 5v reference and a few capacitors / inductors as well so a place that can do all of that on the cheap would be ideal.
edit: additional notes based on clarifying questions people have asked:
- I don't have a specific need aside from just being able to calibrate my bench multimeters up to 6.5 digits
- It was recommended that I send a multimeter in for calibration instead of the resistors and use it as a transfer standard. Fair enough, but whether resistors or a meter, this is the heart of the question: where can I get this done cheaply by a place that is hobbyist friendly? I don't even know where to look.
