Long travel Series A15 Rapid Advance model with measured
travel.
Customer requested a Rapid Advance Model D. They wanted
to measure the travel but only needed a resolution of
1 mm. The solution is a metric lithographed scale graduated
in 1 mm increments added to the standard Model D. Note
the optional extra length slider with hash mark. |
