Verdict Metrinch 1 Dial Test Indicator – 1 3/8" / 36 mm Dial, 0.0005" / 0.01 mm Graduation

Verdict Metrinch 1 is a dual-graduated dial test indicator with both imperial and metric scales on the same dial face, eliminating tool changes and conversion errors on mixed-unit work.

Manufactured by Verdict Gauge Limited — Britain's leading dial test indicator maker, established in Kent in 1938 — the Metrinch 1 (SKU Metrinch1) combines a 1 3/8" / 36 mm dial face graduated in 0.0005" / 0.01 mm increments with a 0.020" / 0.44 mm total measuring range. Designed and made in Britain, every Verdict DTI is built around jewelled bearings, a patented pear-shaped stylus and a precision worm-spiral movement that eliminates cosine error, parallax error and irregular readings.

Key Features

• Measuring range: 0.020" / 0.44 mm total travel suited to both fine alignment and broader inspection work.
