Features
In order to guarantee accuracy, an inspection table is included with the numerical values at the time of inspection.
It does not rust, so it can be handled with bare hands, and there is no need for anti-rust treatment after use, even in humid locations.
Even if the measurement surface is scratched, burrs are less likely to appear.
Higher wear resistance and longer life than steel.
No change over time.
No iron powder etc. will stick to it.
It is equivalent to class 0.
Use
As a reference gauge for accuracy inspection and comparative measurements of calipers, micrometers, dial gauges, etc.
