Dial indicator KM4 SW — 3 mm range, 0.01 mm resolution, Käfer

Dial indicator KM4 SW for precise comparative measurements and short-range quality control in workshops and inspection stations

• 0.01 mm resolution
• 3 mm measuring range
• Shock-protected mechanism
• 0.5 mm per revolution

Reliable small-range precision for inspection tasks

The dial indicator KM4 SW delivers a 0.01 mm resolution across a 3 mm measuring range, enabling fine incremental checks and tight tolerance verification in component inspection. The single-hand dial enables rapid interpretation of small excursions, while the scale layout—combined with a 44.5 mm bezel—improves legibility on the shop floor. The compact format suits comparative set-ups and gauge checks where limited travel and clear repeatable readings are required, translating technical specification directly into measurable process control.

Durable operation through built-in shock protection

Equipped with shock protection, the instrument minimises the risk of mechanism damage during routine handling and accidental knocks commonly encountered in production environments. The protective feature extends service intervals and helps preserve calibration stability, which lowers downtime and reduces total cost of ownership in regular inspection workflows. The mechanical construction prioritises reliability under continuous use, making the indicator a suitable choice for both bench inspection and portable measurement kits.

Faster readings via calibrated revolutions and readable dial

The dial is calibrated so that one hand revolution equals 0.5 mm, simplifying the interpretation of multi-revolution movements and reducing reading errors during rapid checks. The larger bezel diameter enhances contrast and positioning of the index, aiding operators in obtaining consistent measurements. Where traceable documentation is required, the clear graduation and repeatable revolution counting support straightforward recording and quality reporting, aligning metrology practice with production control requirements.

Compact metrology tool for workshops and quality assurance

Designed for ease of integration into existing inspection procedures, the indicator is compact and straightforward to mount in depth gauges, magnetic stands or test fixtures for routine measurement tasks. The combination of small footprint, robust protection and fine resolution makes the instrument ideal for workshop use, first-article inspections and quick in-process checks. For teams seeking reliable, no-frills dimensional control, the device provides a pragmatic balance between precision and everyday usability.
