SERIES 513 — Lever-Type Dial Indicators
Feature icons
• Designed to probe surfaces that cannot be
reached with a normal dial gauge. Useful
both for alignment and for measurement
purposes.
• Mitutoyo’s proprietary new design permits
smooth pointer operation.
• Strong frame provides excellent rigidity and
durability.
• Non-magnetic pointer and contact point
permit reliable operation even in magnetic
environments.
• Clear and concise wide dial face allows
excellent visibility.
• The surface of the crystal is hard-coated for
excellent scratch resistance.
• Flat crystal makes graduations easy to
read. Moreover, the O-ring sealing method
used for the bezel prevents water or oil
penetration. (Note that this type is NOT

waterproof.)
• Six types are available: horizontal, horizontal
(20° tilted face) vertical, parallel, universal,
and pocket, allowing users to select the
model most suited to their needs.
· Horizontal: Standard
· Horizontal (20° Tilted Face): Dial face
inclined 20°, compared with the vertical
type, allows easy reading.
· Vertical: Best suited for centering holes
under the spindle of a machine tool.
· Parallel: The scale can be read from the front,
with the stylus pivoting in a plane parallel to
that of the dial face.
· Universal: The direction of the probe
movement can be freely changed.
· Pocket: Compact type
