Scratch Tester

This motorised apparatus is dedicated to coatings hardness evaluation based on scratching resistance method. A

test panel is clamped and slowly moved whilst a stylus or alternative tool scratches the surface. Oepending on test procedures, specified or variable loads can be applied to obtain different degrees of failure, from trace to destruction. A voltmeter indicates the contact of the tool with the metallic sam pie substrate.

Max. panel size: 100 x 150 x 1.6 mm (0.3 mm coating). Alternatively a simple manually operated version is also available.

Features

• Robust construction, reliable and reproducible results
• Simple maintenance, easy to replace tools
• 220-240 V I 50 Hz
• (110-120 V I 60 Hz on request, please specify)

Pencil Hardness Tester

A traditional method to test the resistance of coatings to scratch. Pencils of progressive hardness, hold by a specific carriage are applied onto the test surface under a force of 750 g, at 45° angle. The surface will be variably damaged, in function of the pencil hardness, thus pass/fail or hardness to failure evaluations are possible.

Features

• Reliable test with high quality pencils
• Standard delivery: specific pencil holder, set of 20 pencils ranging from 9B to 9H, pencil sharpener, 400 grit abrasive paper, carry case.

Barcol Indentation Tester

A handy and easy to use instrument to test the hardness

of soft materials such as metals (aluminium, brass, alloys), plastics, fibreglass, polyesters, leather etc. By pressing the instrument onto the test surface a needle penetrates the material and the degree of hardness is displayed on a dial scale from 0 to 100.

3 ranges available: for soft materials (25-150 BrinelI) - for soft metals/plastic - for very soft material: plastic, leather etc,
