Mitutoyo 2416S Dial Indicator for Professionals: 0-1 Range, 0.001 Graduation

The Mitutoyo dial indicator features a choice between black and white faces, a stem diameter of 0.375 inches, and inch measurements, making it a versatile tool for measuring surface variations in fractional inches. It is designed with a #4-48 UNF thread mount for the contact point, ensuring precise readings. The clarity of the measurements is enhanced by the contrasting hand against the dial's face, whether it be black or white.

Users can select from flat or lug back options, accommodating a variety of mounting preferences. Flat back dial indicators can either be clamp-mounted on the stem or plate-mounted on the rear. On the other hand, lug back indicators are designed with a protruding feature that allows for mounting using a lug, nut and bolt arrangement, usually having the lug installed horizontally. Most lug back indicators also have a back that can rotate to a vertical position for added flexibility.

Designed for longevity and resilience, the stem of the indicator offers a broad clamping range. The frame is constructed without through screw holes to prevent the ingress of dust and water. Additionally, its involute curved lifting lever ensures smooth movement of the spindle, allowing for a tool-less connection at the dovetail joint. These features do not just enhance usability; they also contribute to the device’s compliance with ANSI standards, the Japanese Industrial Standard (JIS) B7503-1997, and the American Gage Design (AGD) benchmark for face and thread sizes, as well as bezel and stem diameters.

Dial readings can be observed in different formats: a balanced dial indicates a three-digit reading, such as 0-10-0, while two-digit readings like 0-100 signify a continuous dial. These balanced dials are specifically designed to measure differences from a predefined surface reference, whereas continuous dials are used for direct readings and typically provide a more extensive measurement range. Additional capabilities include options for jeweled bearings for enhanced sensitivity and precision, a revolution counter that tracks overall changes, and characteristics like waterproof, dustproof, and shockproof designs. The choice of face color—white or black—and reverse reading capabilities for depth or bore gauge measurements further cater to user preferences.

Known also as dial gauges, dial calipers, or probe indicators, these precision measuring instruments serve the critical function of accurately measuring small linear distances and object sizes. By magnifying measurements, the dial facilitates easier reading for users. Dial indicators are particularly prevalent in manufacturing, laboratories, and various mechanical and industrial applications where precise measurements are vital, such as verifying the tolerance variation in workpieces.

Standard dial indicators measure displacement along their axis, while dial test indicators operate with their measurement axis set perpendicular to that of the indicator itself. Both types can be analog, featuring mechanical dials, or electronic with digital displays. Several electronic models can conveniently transfer data to a computer for recording purposes and further analysis.

Founded in Tokyo in 1934, Mitutoyo specializes in precision measuring tools and metrology systems. The company established Mitutoyo America Corporation in 1963, which is now based in Aurora, Illinois.
