Sorry, but I don't think I'm going to be much help.
An artist and papermaker etc I know in London is married to someone who runs a
small company which manufactures the testing equipment for this - and I think
it is sold world-wide.
He ran some tests for me and a few others, but doesn't offer this as a normal
service.
Possibly museums or university departments with an interest in conservation
would have this equipment - I'm sure there are people on this list who would
have more idea than me about it.
