Caliper GEKO 300 mm model G01479 — precision measuring tool 300mm

GEKO caliper model G01479 is a 300 mm precision measuring tool designed for direct linear measurement of external and internal dimensions and depths. Compact and lightweight, this caliper provides reliable manual readings up to 300 mm and is suitable for workshop, hobby and light industrial environments where straightforward distance checking is required.

Advantages

The caliper offers a clear measurement range to 300 mm with a durable sliding scale and jaws for consistent contact with workpieces. Its compact form factor makes it easy to handle and store, and the mechanical scale does not require batteries, which simplifies operation and maintenance. The instrument is built for routine measurement tasks, providing repeatable results when used according to calibration and handling guidelines.

Suitable for

• Measuring external diameters and widths of parts
• Measuring internal diameters of holes and recesses
• Measuring depths of slots and bores up to 300 mm
• Workshop inspection, hobby projects and light assembly checks

Key specifications

• Measurement range: up to 300 mm
• Functions: external, internal and depth measurement
• Scale type: mechanical sliding scale for direct reading
• Construction: fixed beam with movable jaw and depth rod
• Typical materials: metal body and jaws for wear resistance

How to use

Hold the caliper by the fixed beam and slide the movable jaw to approach the object gently until the jaws make firm contact without forcing. For external measurements, place the object between the jaws and read the scale at the indicator. For internal measurements, insert the jaws into the opening and expand until they contact the internal surfaces. For depth measurements, extend the depth rod into the hole or slot and read the scale at the beam. Keep the scale clean and free of chips or dust for accurate readings and avoid tilting the instrument during measurement.

Usage recommendations

Store the caliper in a dry place and protect it from impacts. Regularly clean sliding surfaces and jaws with a soft, lint-free cloth and apply a light protective oil on metal surfaces to prevent corrosion. Verify accuracy periodically using a calibrated gauge or reference standard before critical measurements.
