Pencil Hardness Tester AS-120P

Description
The TOMLIN Pencil Hardness Tester is a simple and effective instrument for evaluating the hardness of various coatings. By applying a pencil lead at a specific angle and pressure, this method determines the coating's resistance based on the trace left behind. It ensures that coatings meet industry-specific hardness standards, making it an essential tool for quality assessments across various industries.

Features

• Industry Standards Compliance: Adheres to GB/T 6739-96, ASTM D3363-00, and GB/T 1727-92 standards.
• Simple and Effective Method: Utilizes pre-sharpened pencils of varying hardness levels, applied consistently to evaluate coating hardness.
• Adjustable Weights: Provides flexibility with load weights of 1000 g, 750 g, and 500 g for versatile testing requirements.

Pencil Hardness Selection
The hardness of the pencil determines the trace left on the coating. A series of pencils, ranging from 6H (hardest) to 6B (softest), allows comprehensive assessment of coating resistance.

Hardness Grades:
6H, 5H, 4H, 3H, 2H, H, HB, B, 2B, 3B, 4B, 5B, 6B

Specifications

• Load Weight: 1000 g / 750 g / 500 g
• Measurement Angle: 45° (between the pencil and measured surface)
• Three Touch Points: Two wheels and a pencil core for stable measurements
• Scratch Speed: Approximately 1 mm/s
