YS1040
Air Cushion Rail
Length of rail: 1,200mm
The rail proves the relative error of experiment on Newton's
second law under given conditions is not greater than 5%.
Type J2125 is an air cushion rail of which the nonstraightness
in longitudinally vertical plane is adjustable and is used together
with a small-size air supply source, type J2126 and a digital
timer, type J0201.
Type J2125-1 is an air cushion rail of which the nonstraightness
in longitudinally vertical plane is adjustable and is used together
with a small-size air supply source ,type J2126-1 and a digital
timer, type J0201-1 |
