Caliper (digital) GEKO 0–300 mm measuring range, 0.01 mm resolution

Digital caliper GEKO with a measuring range of 0–300 mm and 0.01 mm resolution is a compact, handheld precision instrument for linear measurements. It is intended for external, internal and depth measurements and displays numeric results on a clear digital screen. The tool is suited to metalworking, woodworking, mechanical maintenance and hobby tasks where quick, repeatable and accurate dimension checks are required.

Advantages

The caliper offers high resolution of 0.01 mm for precise readings and a wide 0–300 mm measuring range that covers common workshop needs. Its numeric digital display provides fast, unambiguous measurement readouts, while the compact handheld design supports portable use in the workshop or on-site. The instrument measures external, internal and depth dimensions, reducing the need for multiple separate gauges.

Suitable for

• Measuring external diameters and lengths of workpieces in metalworking
• Checking internal dimensions such as bore diameters
• Depth measurements for slots, holes and steps
• Woodworking layout and verification of component dimensions
• Mechanical maintenance, repair and inspection tasks
• Hobbyist and DIY projects requiring precise linear measurement

Key specifications

• Measuring range: 0–300 mm
• Resolution: 0.01 mm
• Measurement functions: external, internal, depth
• Display type: numeric digital display
• Form factor: compact handheld caliper

How to use

Switch on the digital display and zero the display with the jaws closed before starting measurements. For external measurements, place the workpiece between the main jaws and slide the movable jaw until it contacts the part, then read the value directly from the screen. For internal measurements, use the smaller jaws at the top of the caliper and expand them inside the opening to obtain the internal dimension. For depth measurements, extend the depth probe into the hole or slot until it rests on the bottom and read the depth value. Close the jaws and switch off the unit after use to conserve battery life.

Usage recommendations

Handle the caliper on a stable surface and avoid applying excessive lateral force to the jaws. Keep measuring faces clean and free of debris to maintain accuracy. Store the instrument in a protective case or drawer and remove the battery if the device will be unused for extended periods.
