Analog single-sided caliper Gimex 300×90 mm, 0.05 mm resolution (model 201.321)

Analog single-sided caliper Gimex 300×90 mm, 0.05 mm resolution (model 201.321) is a mechanical measuring tool designed for external, internal and depth measurements. The instrument features a single-sided scale with an analogue vernier display that provides manual reading to 0.05 mm. Built for workshop and field use, the caliper is intended for inspection and measurement of parts, profiles and assemblies where straightforward, reliable mechanical measurement is required.

Advantages

This analogue caliper offers a simple, maintenance-friendly design that does not depend on batteries or electronics, ensuring operation in environments where electronic instruments could be impractical. The single-sided scale and vernier allow direct visual reading with 0.05 mm resolution, while the robust mechanical construction is suitable for repeated use in typical workshop and field conditions. The caliper supports measurement of external dimensions, internal diameters and depths with a single instrument.

Suitable for

• Measuring external dimensions of machined parts and profiles
• Checking internal diameters and grooves
• Depth measurements of holes and slots
• Inspection tasks in workshops, maintenance and on-site service
• Educational and training exercises where analogue measurement is required

Key specifications

• Measuring range: 300 × 90 mm
• Resolution (vernier): 0.05 mm
• Measurement functions: external, internal and depth
• Display type: analogue vernier scale (single-sided)
• Construction: mechanical caliper suitable for workshop and field use

How to use

Place the caliper jaws around or inside the object to be measured and slide the movable jaw until it contacts the part. For depth measurement, extend the depth rod into the hole or slot and slide until the base of the caliper rests flat on the reference surface. Read the main scale and the vernier scale together to obtain the measurement to 0.05 mm resolution. Use steady pressure to avoid deformation of the measured part and ensure the measuring faces are clean and free of debris for accurate readings.

Usage recommendations

Store the caliper in a protective case or on a clean surface when not in use, and periodically clean the measuring faces with a lint-free cloth. Avoid exposure to strong impacts, corrosive environments and prolonged moisture. For best accuracy, calibrate or check the instrument against a reference gauge at regular intervals depending on usage intensity.
