Electric scratch testing! We also have a type that can test with two pencils at once!

- This is a testing machine that can be operated electrically instead of manually turning the handle for pencil scratch hardness testing. - We also offer the M2 type, which allows testing with two pencils at once. - The hardness value is determined by scratching the coated surface at a 45° angle, using the hardest pencil that shows no signs of coating damage or scratches. - It is also used for evaluating the scratch hardness of decorative boards and the solvent resistance of enamel wires. <Reference Standards> JIS-(C3003), C3216-4, D0202, (K5400), K5600-5-4, K5651, K6894, K6902, ASTM-D2197, D3363, ISO-15184, IEC-60851-4 【About Catalog Download】 Please request the catalog from the related links below or by contacting us. *For products without a standalone catalog, please request the comprehensive catalog.
