Mitutoyo Dial Indicators & Plunger Dial Gauges

Mitutoyo Dial Indicators – Plunger Dial

A dial indicator is a comparative measuring instrument that shows small linear displacement on a graduated dial or digital display. A plunger type uses a spring-loaded spindle, while a lever type uses a contact arm. Both detect runout, flatness, parallelism and dimensional variation against a reference.

What is a dial indicator?

Dial indicators measure variation rather than absolute size. They compare a feature against a set zero or a reference standard.

Plunger vs lever dial indicators

A plunger dial gauge uses a spring-loaded spindle that moves in line with the contact. A lever dial gauge uses a pivoting arm for tight or angled access. Choose a plunger type for straight-line measurement and a lever type where access is restricted.

Analog vs digital dial gauges

Analog dial gauges read from a graduated dial. Digital indicators show readings on a display and can output data for records and SPC workflows. Both types are available in the Mitutoyo range.

How to choose a dial indicator

Match the gauge type to access requirements: plunger for straight-line work, lever for restricted or angled positions. Consider the measuring range, graduation and whether data output is needed. Confirm exact models, ranges and graduations from the live product listing below.

Mounting with stands and bases

Mount indicators on comparator stands, magnetic bases or fixtures for stable measurement. A rigid mount reduces measurement scatter and ensures consistent contact force. See the Mitutoyo comparator stand range for compatible options.
