Clemen Scratch tester

Scratch hardness testing made simple and precise.

The Clemen Scratch Tester is designed to evaluate the hardness of coatings through a controlled scratch method. Using a 1 mm spherical carbide indenter, the device determines the resistance of paints or coatings to surface damage under increasing loads.

Key Applications

• Scratch hardness testing for paint and coatings.
• Suitable for quality control and lab analysis.
• Complies with leading international standards.

Standards:
ISO 1518-1:2019, EN 13523-12, JIS K 5600-5-5, AS/NZS 1580.403.1
Note: BS 3900-E2, DIN 53799, and ECCA T12 are no longer active but still used in some industries.

How it Works

A 1 mm tungsten carbide ball slides 60 mm over the sample surface. Based on the applied load, the coating shows varying degrees of damage—from surface marking to full failure. You can choose between two models:

1. Clemen MANUAL Version

• Manual movement of the indenter
• Load range: 0–2000 g
• Scratch length: 60 mm
• Sample width: 75 mm
• Dimensions: 410 × 200 × 155 mm
• Weight: 6 kg

Included:

• Elcometer 3000 Manual device.
• 1 mm ball tool.
• Operating instructions.

2. Clemen MOTORIZED Version

For greater precision and repeatability, the motorized Clemen tester automates the scratching process:

• Automatic lowering/lifting of the tool.
• Built-in lamp and voltmeter signal when the substrate is reached.
• Load range: 0–5000 g.
• Sample dimensions: 75 × 150 mm.
• Sample thickness:
  • Standard: 0.5–3 mm.
  • Optional: 5–20 mm.

Operating environment:

• Temperature: 5–40°C.
• Humidity: Max 80% (at 31°C), decreasing linearly to 50% (at 40°C).

Device dimensions: 460 × 280 × 330 mm
Weight: 20 kg

Included:

• Motorized Clemen unit.
• 1 kg weight.
• 1 mm tungsten carbide ball tool.
