I guess the reference to the "standards" means those sold on ebay
US. If so, I would think it is a false expectation this would meet
3ppm acc. guaranteed within a year.
I didn't make any claim as to the ebay units, and don't know anything
about them except what is stated by the seller. I just said that
their claims were "in the ballpark" of what I considered standards of
interest to this group. That was in relation to the OP's proposal of
a 0.1% standard (1000 ppm) -- a standard could miss what I defined as
interesting by quite a lot and still be in the ballpark compared to 1000 ppm.
Best regards,
Charles
