The Käfer analog dial indicator is designed for comparative dimensional inspection in mechanical applications where centesimal deviations must be checked against a reference. The measuring range is 0–10 mm with 0.01 mm graduation, set on a 100-division scale to support direct reading of small variations.

Operation is based on axial movement of the measuring spindle, which is transmitted through the internal mechanism and converted into pointer rotation on the dial. The dial diameter is 58 mm and the bezel is rotatable for zero setting, allowing the reference position to be set before measurement. Two adjustable tolerance markers support go/no-go tolerance monitoring on the dial. The stated measuring force is 0.7 N with ±10% tolerance, and one full revolution of the pointer corresponds to 1 mm of travel.

This dial indicator is intended for comparative checks on machine tools, measuring benches and inspection fixtures, for example when monitoring deviation, checking parallelism and supporting alignment operations during setup and quality control.

Typical use environments include machine shops, metalworking production, maintenance and inspection departments where a robust and repeatable analog indicator is required. Selection is driven by the required 10 mm travel, 0.01 mm graduation, dial size for readability and compatibility of the Ø 8 mm h6 mounting stem with magnetic bases and holders.

This version features a metal housing, a Ø 8 mm h6 measuring spindle and clamping stem made of stainless steel, a hardened and ground clamping stem, replaceable contact inserts and verification using measuring equipment traceable to national and international standards. Delivery is supplied in a protective case. Use is limited to the declared 0–10 mm range and conditions consistent with the stated DIN 878 specification.
