Caliper INSIZE 1138-200 digital 200 mm with long upper jaws, 8-digit display

Digital caliper INSIZE 1138-200 offers a 200 mm measuring range with extended upper jaws designed to reach into deeper bores and narrow grooves. The tool provides clear readings on an 8-digit display, supports metric units, and combines a smooth sliding mechanism with fixed stops for repeatable linear measurements of external, internal, step and depth dimensions in workshop and inspection tasks.

Advantages

The caliper's long upper jaws allow internal measurements in recessed features that standard jaw lengths cannot access. The 8-digit display delivers legible numerical output, reducing reading errors and improving measurement speed. A precise sliding action and well-defined scale ensure stable contact and consistent results during part inspection and setup operations.

Suitable for

• Measuring external diameters and lengths of parts up to 200 mm
• Measuring internal diameters in deep bores or recessed features
• Checking step heights, groove widths and shallow depths
• Routine inspection and workshop setup where quick, repeatable readings are needed

When it may not be suitable

This caliper is intended for general workshop and inspection use with a maximum range of 200 mm; it is not suitable for measurements beyond that range or for applications that require sub-micron accuracy. The tool is optimized for metric units and may not be ideal where inch-only readouts are required unless conversion is acceptable.

Key specifications

• Measuring range: 0–200 mm
• Display: 8-digit digital readout for clear numeric values
• Jaws: long upper (internal) jaws for deep/bore access and standard lower jaws for external measurements
• Measurement types: external, internal, step and depth
• Slide: precision sliding mechanism for stable contact and repeatable results

How to use

For external measurements, close the lower jaws gently onto the part and read the value on the 8-digit display. For internal measurements in deep bores, insert the long upper jaws and open them until contact is made, then read the display. Use the depth measuring blade or the step function where applicable. Ensure the caliper is zeroed before taking critical measurements and move the slider smoothly to avoid overshoot or misalignment.

What to consider before purchase

• Required measuring range — suitable up to 200 mm only
• Necessary jaw length for internal features — long upper jaws provide deeper reach
• Desired display resolution and readability — 8-digit display offers clear numeric output
• Accuracy needs — verify that the caliper's accuracy meets your tolerances for inspection

Usage recommendations

Handle the caliper with steady hands, keep the jaws clean and free of chips, and zero the display regularly. Store in a protective case when not in use and avoid exposing the instrument to heavy impacts or corrosive environments to preserve measurement accuracy and display function.
