Caliper (analog) Gimex 150 mm, 0.05 mm graduation (model 201.020)

Gimex analog caliper model 201.020 offers a 150 mm measuring range with 0.05 mm graduation using a classic mechanical vernier scale. The tool performs external, internal and depth measurements without the need for batteries, making it suitable as a portable precision instrument for workshop, hobby and field use. Its compact construction and clear vernier allow repeatable dimensional checks on metal, wood and model parts where manual accuracy is required.

Advantages

The mechanical vernier design ensures measurement capability without electronics, reducing maintenance and eliminating battery dependence. A 150 mm range combined with a 0.05 mm graduation delivers a balance between reach and fine resolution for common precision tasks. The caliper’s simple, robust construction is convenient for routine inspection, quick checks and environments where electronic devices may be impractical.

Suitable for

• External diameter and length measurements of parts and workpieces
• Internal diameter checks of holes and bores
• Depth measurements of slots, grooves and recesses
• Hobby and model making where manual precision is needed
• Woodworking and light metalworking dimensional checks

Key specifications

• Measuring range: 0–150 mm
• Graduation (resolution): 0.05 mm
• Measurement functions: external, internal and depth
• Scale type: mechanical vernier scale
• Power: none (manual, no batteries required)
• Construction: compact hand tool suitable for workshop and field use

How to use

Place the caliper’s jaws around or inside the object to measure external or internal dimensions, or use the depth rod to probe recesses. Slide the movable jaw until the caliper contacts the workpiece lightly and read the measurement on the vernier scale aligned with the main scale. Ensure jaws are clean and contacts are flush to the surfaces being measured for best accuracy. Zero the reading by closing the jaws fully and noting alignment before taking measurements; no electronic zeroing is required.

Usage recommendations

Handle the caliper gently and store it in a protective case when not in use. Keep the vernier and jaws free of debris and lightly oil the sliding surfaces if used in humid or dusty environments. Avoid applying excessive force when clamping the jaws to preserve the graduation accuracy.
