Mitutoyo 209-916 Outside Dial Caliper Gage 2 Inch

Product Description

The MITUTOYO 209-916 is an outside dial caliper gage designed for precise external groove measurement in machining and inspection environments. It measures external features up to 2 inches (50.80mm) with a graduation of 0.0010 decimal inch, allowing technicians to capture fine dimensional differences quickly and reliably. The gage uses a ball-to-ball contact point configuration, which is well suited for seating into grooves and curved surfaces. Machinists, quality control inspectors, and tool room technicians use this instrument on the shop floor or at an inspection station to verify outside groove dimensions to tight tolerances.

The MITUTOYO 209-916 is suited for measuring outside grooves in turned or milled components. With a groove depth capacity of 0.1100 decimal inch (3.00mm) and a groove width of 3.0000 decimal inch, it accommodates a range of standard groove profiles encountered in precision manufacturing. It is intended for use in industrial production, quality assurance, and tool and die applications where consistent, repeatable outside diameter and groove measurements are required.

Key Features

• Measurement range: 0 to 2 inches (0 to 50.80mm)
• Graduation of 0.0010 decimal inch for fine resolution readings
• Ball/ball contact point type for reliable seating in grooves and curved surfaces
• Groove depth capacity: 0.1100 decimal inch (3.00mm)
• Groove width capacity: 3.0000 decimal inch
• Compact form factor sized for bench and floor-level inspection use

Compatibility

Designed as an OEM-style outside dial caliper gage for use in standard industrial measurement and inspection applications requiring external groove measurement with ball contact points.

Installation Notes

This instrument is used by machinists and quality control technicians and requires no installation in the traditional sense. Before use, zero the dial indicator face with the contact points closed to verify calibration. Keep contact points clean and free of chips or coolant residue to ensure accurate readings. Handle with care to avoid dropping, which can shift the dial mechanism and compromise measurement accuracy.
