The 2046S from Mitutoyo is a standard multi revolution dial indicator suited to general measurement applications. The dual reading scale aids measurement in both directions. The outer clamp and lifting lever (optional) can be attached to either the right or left side. These parts can easily be installed and removed without tools. Secure adhesion between the bezel and crystal as well as the use of an O-ring prevents water or oil penetration and the spindle is made of high strength quench hardened stainless steel which resists arduous use. Application of a hard coating on the surface of the crystal makes the gauge highly scratch and chemical resistant.
