In comparison with HELICHECK PRO, HELICHECK PLUS also enables the high-precision measurement of micro tools with diameters from 0.1 mm. Even the smallest details are visible and measurable thanks to the special reflected light unit and the diffusor. All the advantages of HELICHECK PRO are naturally also present in this optical CNC measuring machine. The linear measurement deviation in accordance with VDI/VDE 2617 is E1 = (1.4 + L/300)µm.
