Mitutoyo caliper 150 mm, model 530-101, graduation 0.05 mm is a compact manual measuring instrument designed for linear external, internal and depth measurements up to 150 mm. The caliper provides 0.05 mm graduation for finer reading than standard 0.1 mm rules, making it suitable for simple workshop, inspection and hobby tasks that require clearer visibility of small increments. The tool uses sliding jaws and a fixed scale for direct reading and stable positioning during measurement.
Advantages
The caliper offers a consistent manual measuring action with durable stainless-steel construction for resistance to wear in everyday workshop use. Its 150 mm measuring range covers common component sizes while the 0.05 mm graduation improves resolution for basic precision checks. The simple, non-electronic design requires no batteries and reduces maintenance needs, and the sliding jaw arrangement supports external, internal and step measurements with straightforward operation.
Suitable for
- Workshop component sizing and inspection
- Mechanical assembly and fitting checks
- Hobby and model-making measurements
- Basic quality control in small production or repair settings
Key specifications
- Measuring range: up to 150 mm
- Graduation (resolution): 0.05 mm
- Measurement types: external, internal, depth/step
- Material: stainless steel sliding jaws and beam
- Scale type: manual vernier-style/non-electronic scale
How to use
Place the caliper jaws around or inside the object to be measured and slide the movable jaw until it makes gentle contact with the measured surface. Read the measurement directly from the scale using the vernier graduation to determine the 0.05 mm increment. For depth or step measurements, extend the depth rod or use the step face and align the fixed and sliding faces against the surfaces being measured. Maintain light, consistent contact pressure to avoid deformation of the workpiece or measurement error.
Usage recommendations
Store the caliper in a clean, dry environment and wipe the scale and jaws after use to prevent debris buildup. Avoid exposing the tool to strong magnetic fields or corrosive chemicals. When higher precision or data output is required, consider using digital or dial variants with data interfaces, but for routine checks the manual 0.05 mm caliper provides reliable, low-maintenance measurement.
