Electronic Caliper Unimet L-190140400 150 mm measurement tool

The Electronic Caliper Unimet L-190140400 150 mm measurement tool is a digital caliper designed for accurate external, internal and depth measurements within a 150 mm range. It features a clear digital readout and simple control layout for fast dimension checks in workshops, laboratories and home environments. The tool is compact and portable, suitable for measuring parts, verifying tolerances and checking fits during production, maintenance and DIY projects.

Advantages

The caliper offers precise linear measurement with a digital display that reduces reading errors compared to analog scales. Its compact 150 mm measuring range makes it convenient for small to medium-sized workpieces while remaining lightweight and easy to handle. The instrument is versatile, providing external, internal and depth measurement functions in a single device, and is built for repeatable results in routine quality control and verification tasks.

Suitable for

• Measuring external dimensions of components and parts
• Checking internal diameters and hole sizes
• Depth measurement of grooves, steps and recesses
• Dimensional verification during assembly, maintenance and repair
• Hobbyist and DIY projects requiring accurate small-part measurement

Key specifications

• Measuring range: 0–150 mm
• Measurement functions: external, internal, depth
• Display type: digital LCD readout
• Material and construction: compact handheld body suitable for workshop use
• Portable design for field and bench work

How to use

Place the caliper jaws around or inside the object to be measured and move the sliding scale until the jaws contact the surfaces. For depth measurements extend the depth rod into the feature and read the value on the digital display. Ensure the measuring faces are clean and parallel to the measured surfaces and allow the display to stabilize before recording readings. Use the zero function at any position if relative measurements are required.

Usage recommendations

Store the caliper in its protective case when not in use and avoid exposing it to strong shocks, liquids or magnetic fields. Periodically clean the jaws with a soft cloth and check battery condition to maintain reliable display performance. For best accuracy, perform measurements at stable ambient temperature and avoid applying excessive force to the jaws.
