Might you consider a vernier caliper...rugged, accurate, cheap and
reading
one is easy and becoming a lost art.


Not really. Every lab science course I have taken in the last 2 years
has required students to read vernier scale instruments.

It's a lost art for me - I can't see the damn scales anymore!
