Digital Indicator INSIZE 12.7 mm / 0.001 in (model 2103-10F)

The Digital Indicator INSIZE 12.7 mm / 0.001 in (model 2103-10F) is a portable contact measuring instrument designed for precise measurement of displacement, thickness and runout. It features a 12.7 mm measuring range and a digital readout with 0.001 in resolution to provide clear, repeatable readings suitable for workshop inspection and quality-control tasks. The compact housing and numeric display facilitate setup and measurement in confined spaces and on production lines where fine incremental accuracy is required.

Advantages

This digital indicator provides high-resolution measurements with a straightforward digital display for quick interpretation. Its compact, handheld design allows easy positioning against workpieces, and the durable contact probe ensures consistent contact with the measured surface. The instrument delivers reliable incremental readings for setup, inspection and comparative measurement without requiring complex calibration procedures for routine use.

Suitable for

• Measuring displacement and runout on shafts and spindles
• Thickness checks of sheet metal, plates and components
• Workshop setup and alignment tasks
• Quality control inspections and pass/fail comparisons
• Bench measurements and comparative gauging in production

Key specifications

• Measuring range: 12.7 mm
• Resolution: 0.001 in
• Display: digital numeric readout
• Contact probe type: precision contact tip suitable for surface contact
• Form factor: portable, handheld indicator

How to use

Position the indicator so the contact probe is perpendicular to the measured surface and ensure stable support to avoid measurement error from movement. Zero the display at a reference point if required, then displace the probe against the test surface to read the change in position on the digital display. For runout checks, mount the indicator on an appropriate holder and rotate the workpiece to observe variation. Follow ordinary handling practices to avoid shock to the probe or display.

Usage recommendations

Store the indicator in a protective case when not in use, keep the contact tip clean and inspect for wear periodically. Use stable fixturing and avoid excessive lateral forces on the probe to maintain accuracy. For consistent results, allow the instrument to acclimate to workshop temperature before critical measurements.
