Dial Flatness Gauges
Slide these gauges across surface plates, lapping plates, and other precision surfaces and a variance indicator (required but not included with all gauges) helps you determine if their flatness is within tolerance. The variance indicator displays the amount of deviation as you move the flatness gauge.
