I need to get the durometer tested on a rubber part. This part just
came in, the customer doesn't know what the durometer is, and he needs
parts friday. I would just order a durometer overnight but the
cheapest I can find is $280.00. The whole job isn't worth it. Since it
may or may not turn into more work, I'm reluctant to spend the money
on it. The customer said I only need to be close, not perfect on the
hardness. Is there a way I can approximate it with a weight and a
properly shaped probe tip?
Thanks,

Perhaps you could use a dial indicator with a spring and either a
conical or ball foot.

Find a material specimen of known durometer that most closely matches
the measurement on the part to be matched.
