wide ruler

This is a widened product that can be used with a level placed on it.
As a standard ruler, it is ideal for parallel and straight measurements.
Used for inspection of operating accuracy of machines, assembly of precision machinery, installation and inspection of turbines in power plants, etc.
Straightness and parallelism (JIS height variation) are products that have passed the JIS ruler standard (JIS B7514).
Available in hardened and non-hardened products.

*Straightness measurement

Straightness is measured by supporting a straight edge at the point of minimum deflection.

The distance from both ends to the support position P is

P = 0.2203 x L (L = total length mm)
