Dial/Digital Indicator Applications
Lens thickness measurement • Thickness of concave-convex lenses and surfaces can be measured. (Contact point, Anvil: hardened steel) • Anvils and contact points are interchangeable to enable concave surfaces to be measured. • Provided with a ball point as standard.
