Digital Caliper MEGA 150 mm / 0.02 mm - model 20513

Digital caliper MEGA 150 mm / 0.02 mm - model 20513 is an electronic measuring tool designed for accurate linear measurements up to 150 mm. The instrument provides a clear digital readout in metric units and supports internal, external and depth measurements. Its 0.02 mm resolution enables finer readings than standard 0.1 mm calipers, making it suitable for workshop tasks, production quality control and precise DIY applications where repeatable measurements are required.

Advantages

The digital display delivers fast, easy-to-read results while the compact stainless steel jaws and depth probe allow versatile measurement modes. The caliper is lightweight for handheld use and offers a smooth slider for quick positioning. Metric units are presented directly on the screen, eliminating the need for manual conversions. The design balances accuracy and usability for routine measuring tasks.

Suitable for

• Measuring external dimensions of machined parts and components
• Inspecting internal diameters such as bores and slots
• Depth measurement of holes, recesses and steps
• Quality control checks in small-batch production
• Precise measurements for woodworking and metalworking DIY projects

Key specifications

• Measuring range: 150 mm
• Resolution: 0.02 mm
• Measurement modes: external, internal, depth
• Display type: digital LCD readout
• Material: stainless steel jaws and beam
• Power: battery powered for portable operation

How to use

Before use, wipe measuring faces clean and zero the caliper with the jaws fully closed according to the manufacturer procedure. For external measurements, place the object between the outer jaws and slide until contact is made without excessive force. For internal measurements, insert the inner jaws into the feature and open to contact. For depth measurements, extend the depth probe into the hole or recess and read the value from the display. Take multiple readings when necessary and re-zero periodically to maintain accuracy.

Usage recommendations

Store the caliper in a protective case when not in use, avoid exposure to strong magnets or excessive moisture, and replace the battery promptly to prevent display errors. Regularly clean and lightly oil moving parts to ensure smooth operation and consistent readings.
