Designed for precision measurement of shafts, components and finished parts in workshops and quality control, it provides clear digital readout and reliable repeatability.

## Long description

INSIZE 3109-150A is a digital micrometer designed for accurate external measurements in the 125–150 mm range. The instrument combines a clear digital readout with a ratchet stop mechanism to ensure consistent measuring pressure and carbide measuring faces for improved wear resistance and long-term accuracy. It is intended for workshop and quality control environments where repeatable, precise measurement of shafts, components and finished parts is required.
Advantages
The ratchet stop provides repeatable contact force, reducing measurement variation caused by operator pressure. Carbide measuring faces increase durability and resist wear when measuring hard materials. The digital display offers quick, easy-to-read results and minimizes reading errors compared with analogue scales. The micrometer’s construction and measuring range make it suitable for medium-sized external dimensions while maintaining stable accuracy.
Suitable for
Measuring external diameters of shafts and cylindrical parts within 125–150 mm
Inspection of finished components in production and quality control
Dimensional verification in workshops, toolrooms and maintenance departments
Applications requiring repeatable contact pressure and wear-resistant anvils
Key specifications
Measuring range: 125–150 mm
Measuring faces: carbide for improved wear resistance
Contact mechanism: ratchet stop for consistent measuring force
Readout: digital display for direct numeric reading
Application: external dimensional measurement of shafts and machined parts
How to use
Before measuring, clean the measuring faces and the workpiece to remove oil and debris. Place the part between the anvils and rotate the thimble until the ratchet slips to apply consistent contact pressure. Read the value on the digital display and record or transfer it as required. For repeated measurements, ensure the same seating and contact technique are used to maintain repeatability. Periodically check zero calibration according to your quality procedures.
Usage recommendations
Store the micrometer in a protective case when not in use, avoid exposing it to excessive shock or moisture, and perform regular calibration checks to maintain measurement accuracy. Use the ratchet stop consistently to reduce operator-induced variation and protect the carbide faces from impacts that could cause chipping.
