Caliper Gimex analog 300 mm 0.05 mm (model 201.054)

The Caliper Gimex analog 300 mm 0.05 mm (model 201.054) is a mechanical vernier caliper designed for precise metric measurements up to 300 mm. It provides external, internal and depth measurements using a vernier scale with 0.05 mm resolution, and operates without batteries or electronic components. The tool is suitable for workshop use, hobby projects and general mechanical measuring tasks where a reliable analogue instrument is preferred.

Advantages

The caliper offers accurate metric readings to 0.05 mm through a finely graduated vernier scale, ensuring repeatable results in manual measurements. Its mechanical design delivers consistent performance without dependence on power sources or electronics, making it robust in various environments. The 300 mm measuring range covers most small-to-medium sized parts encountered in workshops and hobby applications, while the simple construction allows easy maintenance and long-term service life.

Suitable for

• Measuring external dimensions of components up to 300 mm
• Measuring internal diameters and grooves
• Depth measurements of holes and recesses
• Workshop quality control and part inspection
• Hobbyist and DIY mechanical projects

Key specifications

• Measuring range: 0–300 mm
• Resolution: 0.05 mm (vernier scale)
• Measurement functions: external, internal and depth
• Scale type: analog vernier
• Power source: mechanical (no batteries)

How to use

To measure an external dimension, close the caliper jaws around the workpiece and read the main scale and vernier alignment for the 0.05 mm resolution. For internal measurements, open the internal jaws inside the hole or slot and read the scales in the same manner. For depth measurements, extend the depth rod into the hole or recess and read the combined scale values. Ensure the sliding surfaces are clean and the jaws are gently seated against the part without excessive force. Zero the reading by closing the jaws and confirming the vernier aligns with the main scale before taking critical measurements.

Usage recommendations

Store the caliper in a dry, dust-free place and avoid exposure to strong magnetic fields or corrosive substances. Clean sliding surfaces and measuring faces with a soft, lint-free cloth and light machine oil when needed. Handle the instrument carefully to prevent knocks or drops that could affect accuracy. For consistent results, calibrate or check the caliper against gauge blocks or a reference standard periodically.
