Caliper INSIZE SUWMIARKA SPEC. 11-150 digital 0.01 mm accuracy 1520-150

INSIZE SUWMIARKA SPEC. 11-150 (model 1520-150) is a digital caliper designed for precise dimensional measurement in workshop and inspection environments. The tool offers a measuring range from 11 mm to 150 mm with a numeric digital readout and 0.01 mm resolution, supporting internal, external and depth measurements. Compact measuring jaws and a fine adjustment mechanism enable controlled, repeatable readings suitable for metalworking, engineering and quality control tasks.

Advantages

The digital caliper provides high-resolution readings with a 0.01 mm increment, ensuring accurate measurement of small tolerances. Its digital display delivers clear numeric values, reducing manual reading errors. A fine adjustment feature allows smooth, controlled jaw movement for repeatable contact and consistent results. The caliper’s compact jaws and depth probe adapt to a variety of measurement points, while its robust construction suits routine workshop use.

Suitable for

• External diameter and thickness checks of machined parts
• Internal bore and slot measurements
• Depth measurement of steps, recesses and holes
• Incoming inspection and quality control sampling
• General engineering and maintenance measurements

Key specifications

• Measurement range: 11–150 mm
• Resolution: 0.01 mm
• Measurement modes: external, internal, depth
• Display: digital numeric readout
• Adjustment: fine adjustment mechanism for controlled jaw movement
• Jaw type: compact measuring jaws for confined spaces

How to use

Before measurement, clean the caliper jaws and the object surface to remove debris. Switch on the instrument and zero the display at fully closed jaws. For external measurements, place the object between the jaws and close gently using the fine adjustment until firm contact is achieved; read the value on the digital display. For internal measurements, use the internal jaws and expand until they contact the internal surfaces. For depth measurements, extend the depth probe into the feature and read the display. After use, wipe the caliper clean, retract the jaws and switch off to preserve battery life.

Usage recommendations

Store the caliper in a protective case when not in use, avoid exposing it to strong impacts, liquids or magnetic fields, and perform periodic calibration checks against gauge blocks or reference standards to maintain measurement accuracy.
