Caliper Gimex 300 mm model 201.321.1, 0.05 mm resolution, 12 jaws

Gimex 300 mm caliper model 201.321.1 is a precision measuring instrument with 0.05 mm resolution and 12 jaws for internal, external and depth measurements. It is designed for accurate dimensional checks of parts, pipes and components in workshops, for hobbyists and for technical inspections. The compact 300 mm measuring range and clear scale allow routine measurement tasks to be performed with repeatable results.

Advantages

The caliper provides fine resolution of 0.05 mm for improved measurement accuracy and comes with 12 jaws that enable versatile use on internal and external diameters as well as depth measurements. Its 300 mm range covers a wide variety of small to medium-sized parts, and the construction offers stable contact points to reduce measurement error during routine checks.

Suitable for

• Measuring external dimensions of machined parts and components
• Checking internal diameters of pipes, holes and fittings
• Depth measurements of slots, steps and bores
• Workshop quality control and routine inspection
• Hobby and model making precision checks

Key specifications

• Measuring range: 0–300 mm
• Resolution: 0.05 mm
• Jaws: 12 jaws for internal and external measurements
• Measurement types: external, internal and depth
• Construction: compact design suitable for bench and portable use

How to use

Position the caliper so the appropriate jaws contact the measured surface; for external measurements close the external jaws around the object, for internal measurements insert the internal jaws into the hole and expand until they contact the inside surface, for depth use the depth rod and extend it to the measurement point. Read the scale at eye level to avoid parallax error and ensure contacts are firm but not forcefully clamped to prevent deformation of the workpiece. Zero the tool or note the reference before taking comparative measurements.

Usage recommendations

Keep measuring faces clean and free of debris, store the caliper in a protective case when not in use, and avoid exposure to strong impacts or corrosive environments. Calibrate or check accuracy periodically against gauge blocks or a reference standard to maintain reliable results.
