View full detailsFlatness gauges are used for visual flatness inspection, or with the use of feeler gauges. They are divided into knife-edge, flat, and H-type. They come in various qualities (flatness accuracy) based on the DIN 874 standard. These categories are in order GG2 (lowest) GG2 - GG1 - GG0 - GG00 (highest)
The straight edges (straight edges) are standard inspection tools used to verify the straightness and flatness of large surfaces. Unlike common rulers, straight edges focus on the edge accuracy of their working edge, which serves as an absolute reference guide for identifying deviations and waviness.
