3 Overview
Height caliper is used to measure the height position of the workpiece surface and the measuring precision crossed. Its main structure was
Height vernier caliper (see Figure 1), and several significant height caliper (see Figures 4 and 5) with a table height caliper (see Figures 2 and 3).
