## Long description

Electronic caliper Proline 20516 provides precise linear measurement within a 150 mm range with stated 0.03 mm accuracy. This handheld measuring tool supports inside, outside, depth and step measurements and presents results on a clear electronic digital readout. The caliper uses a metric scale and battery-powered electronics for rapid numerical feedback, making it suitable for workshop tasks, hobby projects and general inspection work that requires sub-millimetre resolution.
Advantages
The caliper combines a compact 150 mm measuring range with an electronic display for straightforward, repeatable readings. Its 0.03 mm stated accuracy enables finer measurement than common mechanical verniers, while the battery-powered digital encoder reduces parallax errors and speeds up dimension checks. The tool’s design supports multiple measurement modes (inside, outside, depth, step) so one instrument covers a variety of tasks. Lightweight construction and a portable footprint make it convenient to carry in a toolbox or on a workbench.
Suitable for
Dimensional checks of small machined parts and components
Workshop and maintenance measurement tasks
Hobbyist projects requiring sub-millimetre accuracy
Quality control and inspection where fast numeric readout is required
Measuring internal diameters, external widths, depths and step heights
Key specifications
Measuring range: 150 mm
Declared accuracy: 0.03 mm
Measurement functions: inside, outside, depth, step
Display type: electronic digital readout
Scale: metric
Power: battery-operated
How to use
Before measuring, ensure the caliper jaws are clean and the battery is installed and functional. Zero the display with the jaws fully closed, then place the jaws or depth rod on the feature to be measured. Read the dimension directly on the electronic display and, if needed, repeat the measurement to confirm repeatability. For internal measurements, open the inside jaws until they contact the bore; for depth measurements, extend the depth rod vertically into the feature. Handle the instrument gently to avoid shocks and maintain calibration.
Usage recommendations
Store the caliper in a protective case when not in use, avoid exposure to strong magnetic fields and excessive moisture, and replace the battery when display dimming or erratic readings appear. Periodically check zero and, if required, have the instrument calibrated according to your quality procedures to retain the stated 0.03 mm accuracy.
