Digital Caliper EPM E-400-5000 — 150 mm measuring range, 0.01 mm resolution

EPM E-400-5000 is a digital caliper with a 150 mm measuring range and 0.01 mm resolution. It is designed for external, internal and depth measurements and provides a fast digital readout suitable for workshop, hobby and inspection tasks. Compact and lightweight, this caliper is intended for precision checks, part fitting and general dimensional control in manufacturing and maintenance environments.

Advantages

The caliper offers a clear digital display with 0.01 mm resolution for accurate reading and repeatable measurements. Its compact construction and lightweight design make it easy to handle and store. Designed to measure external, internal and depth dimensions, the tool supports multiple measurement tasks without changing instruments. Battery-powered electronics ensure quick startup and consistent digital output for routine use.

Suitable for

• Workshop measurement and part verification
• Hobby and DIY projects requiring precise dimensions
• Quality control and inspection of small components
• Maintenance tasks where dimensional checks are needed

Key specifications

• Measuring range: 150 mm
• Resolution: 0.01 mm
• Measurement functions: external, internal and depth measurements
• Display type: digital readout
• Form factor: compact and lightweight caliper
• Power: battery-operated

How to use

Before measuring, ensure the caliper is clean and the battery is functional. Turn on the digital display and zero the jaws at the fully closed position. For external measurements, place the object between the outer jaws and slide until a snug fit is achieved, then read the value on the display. For internal measurements, use the inner jaws and expand until they contact the internal faces. For depth measurements, extend the depth rod into the feature to be measured. After use, wipe the caliper clean, retract the jaws, and switch off the unit to preserve battery life.

Usage recommendations

Store the caliper in a protective case when not in use and avoid exposing it to strong shocks, dust or liquids. Calibrate the instrument periodically according to workplace quality procedures to maintain measurement accuracy. Use gentle, consistent pressure when closing the jaws to avoid distortion of readings, and replace the battery when display brightness or stability decreases.
