Caliper GEKO 200 mm two-jaw measuring caliper with plastic case, model 01478

GEKO two-jaw measuring caliper with 200 mm range, model 01478, is a manual vernier-style instrument supplied with a plastic storage case. It is designed for straightforward external and internal linear measurements up to 200 mm, providing tactile control and clear reading for general workshop, hobby and inspection tasks. The tool is suitable for checking component dimensions, verifying part diameters and simple quality-control measurements where a mechanical caliper is preferred over digital alternatives.

Advantages

The two-jaw design enables both external and internal measurements without changing attachments, while the vernier scale offers reliable precision without batteries or electronics. Its 200 mm measuring range covers common workshop needs for metalworking, woodworking and DIY projects. Supplied with a protective plastic case, the caliper is easier to store and transport, reducing the risk of damage or misalignment during handling.

Suitable for

• Measuring external diameters and lengths of parts
• Measuring internal dimensions such as bores and slots
• Routine dimensional checks in a workshop or hobby environment
• Component verification during assembly and repair tasks

Key specifications

• Measuring range: 0–200 mm
• Measurement method: manual vernier (mechanical)
• Measurement types: external and internal using two jaws
• Included accessory: plastic storage case for protection and transport
• Construction: metal caliper body with precision jaws

How to use

Place the caliper jaws around or inside the feature to be measured and gently close until the jaws contact the workpiece without forcing. Read the main scale and vernier scale in combination to obtain the measurement. For internal measurements, use the upper jaws and ensure the caliper is aligned squarely with the measured surface. After use, clean any debris from the jaws, retract the slider to its resting position and store the caliper in the supplied plastic case to protect the scale and jaws.

Usage recommendations

To maintain accuracy, avoid exposing the caliper to heavy impacts, moisture or strong magnetic fields; periodically clean and lightly oil sliding surfaces and store the tool in its case when not in use. For tasks requiring traceable or higher-precision readings, consider calibration against a reference standard.
