h2>Overview
The Cometech GI-M010 Portable Pencil Hardness Tester is a motorized, self-contained unit that applies pencils of incremental hardness grades (6B to 9H) to a coated surface at a fixed 45° angle and a controlled load up to 10N, in accordance with the Wolff Wilborn method.
Unlike manual handheld pencil testing, the GI-M010 drives the pencil across the specimen at a constant, repeatable speed of 10mm/sec — eliminating operator-induced variation and ensuring reproducible hardness determination.
Its compact size (280×130×226mm) and low weight (4.8kg) make it fully portable for both lab and production-floor use.
Key Features
- Wolff Wilborn motorized method — fixed 45° angle, controlled load, and constant 10mm/sec test speed for repeatable results.
- Load range 0–10N — adjustable to meet various test standard load requirements.
- Pencil grade range: 6B to 9H (DIN or JIS standard pencils available as optional accessory).
- Multi-standard compliance: ASTM D3363, ECCA T4, MIL C27 227, NEW 5350, SIS 184187, SNV 37113, JIS-C3003/D0202.
- Applicable to single and double-layer baking varnish, paint, and surface coatings on metal, plastic, glass, and electronics housings.
- Portable and lightweight (4.8kg) — suitable for both lab and production floor quality control.
