Workshop caliper MEGA 150 mm, accuracy 0.02 mm model 20511

Workshop caliper MEGA 150 mm, accuracy 0.02 mm model 20511 is a compact vernier-style measuring tool intended for linear measurements up to 150 mm. It is designed for external, internal and depth measurements and offers fine graduations with 0.02 mm resolution, making it suitable for precise workshop and hobby tasks. The caliper is lightweight, portable and compatible with common measuring routines in metalworking, woodworking and inspection work.

Advantages

The caliper provides a clear graduated scale with 0.02 mm resolution for detailed readings. Its multipurpose jaws allow external and internal measurements while the depth probe enables accurate depth checks. The 150 mm measuring range covers most small to medium workshop needs and the compact form factor supports easy handling and storage. Durable construction ensures repeated use in workshop environments.

Suitable for

• Measuring external diameters, lengths and widths of components
• Checking internal dimensions such as bore diameters and slot widths
• Measuring depth of holes, grooves and recesses
• General inspection and quality control in small workshops and hobby projects
• Woodworking layout and verification of cut dimensions

Key specifications

• Measuring range: 0–150 mm
• Resolution: 0.02 mm
• Measurement types: external, internal and depth
• Construction: workshop-grade caliper designed for repeated manual use
• Form factor: compact, hand-held instrument suitable for bench and field use

How to use

Hold the caliper by the beam and slide the movable jaw to bring the measuring faces into contact with the workpiece for external measurements, or insert the internal jaws into a bore and open them until they contact the internal faces for internal measurements. For depth measurements, extend the depth probe into the hole or recess until it contacts the bottom. Read the indicated value on the graduated scale with 0.02 mm resolution, ensuring the jaws are clean and properly aligned with the measured surfaces. Use consistent light pressure to avoid measurement error.

Usage recommendations

Keep measuring faces clean and free of debris, and store the caliper in a protective sleeve or case when not in use. Check zero setting before each measurement session and avoid exposing the instrument to heavy impacts, strong magnetic fields or corrosive substances to maintain accuracy and longevity.
