On the bench or at the machine, the Mitutoyo Series 2 dial indicator takes comparative measurements, pairing a 0-1 inch measuring range with a 0-100 dial reading in a standard diameter body. Conforming to ANSI/AGD standards, this precision dial indicator serves inspection benches, machine setup, fixture and jig checks, and gauge stations.
The stem and spindle are hardened, high-strength steel, and a jeweled bearing keeps the movement low friction for smooth, precise operation. Secured adhesion between frame and crystal, backed by an O-ring, blocks water and oil from working in through the front face, and the crystal itself carries a scratch and glare-resistant coating. The lug back mounts the indicator to fixtures and stands, and the outer clamp and optional lifting lever attach on either side without tools.
Key features:
• Carbide tipped contact point holds its accuracy through long, repeated use
• Shock-proof mechanism absorbs the jolt of sudden spindle retraction to protect the movement
• Machine ground rack gear fits tighter for increased accuracy
• Rigid bearing plate reduces retracing error by up to 20%
• 4-screw mounting and a frame with no through screw hole add impact resistance and dust resistance
• Offset spindle bushing gives trouble-free stem clamping and a longer clamping range
How does a dial indicator improve machine setup?
A Mitutoyo dial indicator turns small alignment errors into readable needle movement, so you can true vises, align fixtures, and check runout before cutting.
Applications: runout checks on spindles and shafts, vise and fixture alignment, flatness and parallelism checks, part comparison against masters, machine tram checks, repeatability testing.
Industries: precision machining, toolmaking, quality assurance, equipment maintenance, metal fabrication.
Users: setup operators, machinists, maintenance technicians, QC inspectors, toolmakers.
What is a dial test indicator, and is this the same tool?
A dial test indicator reads small movements through a pivoting lever tip, while a dial indicator like this Mitutoyo Series 2 reads through a spindle that travels in line with the dial face. The lever style suits hard-to-reach surfaces and small sweep checks, and the spindle style covers everyday bench measurement, runout checks, and fixture setting with longer travel.
Does the 0-100 dial show a size or a deviation?
You read deviation, not absolute size. Seat the contact point on your reference, set the dial to zero, and any needle movement then shows how far the measured surface sits above or below that reference on the 0-100 dial reading. Watch direction as well as amount, since rise and fall of the needle separate high spots from low.
Is a dial gauge the same thing as a drop indicator?
Yes, in everyday shop language. Dial gauge, drop indicator, and dial indicator generally name the same plunger-style measuring tool, and this Mitutoyo Series 2 answers to all three. When you order, check the mounting back rather than the name. This model carries the lug back, one of the two backs offered in the line, so match it to the way your stand or fixture clamps.
