Workshop Vernier Caliper MEGA 150 mm / 0.02 mm (model 20510)

Workshop Vernier Caliper MEGA 150 mm / 0.02 mm (model 20510) is a mechanical measuring instrument designed for accurate external, internal and depth measurements in metalworking, repair and maintenance environments. The tool combines a 150 mm measuring range with a 0.02 mm vernier graduation to enable precise manual readings and repeatable dimensional checks. Its robust construction and clear scale make it suitable for regular use in a workshop setting where durability and straightforward operation are required.

Advantages

The caliper provides high-resolution readings with 0.02 mm graduation, enabling fine measurement control without electronic components. Its sturdy build is intended for workshop conditions, resisting routine handling and providing stable jaws for repeatable results. The clear vernier scale supports fast visual reading and reduces interpretation errors during inspection and adjustment tasks.

Suitable for

• Measuring external dimensions of machined parts and components
• Measuring internal diameters of holes and bores
• Measuring depths of slots, steps and recesses
• Routine workshop inspection, quality control and maintenance checks

Key specifications

• Measuring range: 0–150 mm
• Graduation / resolution: 0.02 mm (vernier)
• Measurement functions: external, internal and depth measurements
• Display type: mechanical vernier scale (manual reading)
• Construction: workshop-grade metal frame and jaws

How to use

Place the caliper jaws around or inside the feature to be measured and slide the movable jaw until it contacts the workpiece lightly but firmly. For depth measurements, use the depth rod at the end of the slide and ensure the caliper beam sits squarely on the reference surface before reading. Read the main scale and the vernier scale together to determine the measurement to the nearest 0.02 mm. Maintain consistent contact force and alignment to reduce measurement variation and repeat readings to confirm results.

Usage recommendations

Store the caliper in a clean, dry place and protect the scale and jaws from shocks and heavy impacts. Clean contact surfaces before measuring, avoid exposure to corrosive substances, and periodically check jaw alignment and sliding smoothness. Where higher throughput or digital readout is required, consider using this caliper alongside electronic measuring tools, while retaining it for reliable manual measurements.
