DH-7 dual-purpose measuring instrument for surface roughness and contour

Swiss AsmetoDH-7 dual-purpose measuring instrument for surface roughness and contour, equipped with a built-in thermal printer, can print numerical values, graphics, and P&L ratios. The diamond tip position display can prevent damage to the diamond tip, especially when measuring hidden areas The cut-off value starts from 0.08mm, which allows users to solve most difficult measurement problems We can supply many special measuring anvils and manufacture them according to customer requirements
