Buchholz Indentation Tester Paint Hardness Indentation Length 1kg

Product Features & Attributes
This Buchholz indentation tester is used to determine paint film hardness through indentation testing. It is common equipment for coating hardness testing in paints, automotive, furniture and other industries. Hardness is expressed as the reciprocal function of indentation length (indentation resistance) under specified test conditions.

Working Principle: Place the indentation device on the dried coating surface. Under fixed load (500±5g) and device weight (1kg±5g), hold for a specified time to form an indentation on the coating surface. Measure the indentation length with a reading microscope, calculate indentation resistance as the reciprocal of indentation length to evaluate coating hardness.

Structural Features:

• Compact and well-designed structure

• Attractive appearance, simple operation

• High precision control

• Excellent performance, wide application range

Technical Parameters:

• Indentation device weight: 1kg±5g

• Indentation load: 500±5g

• Reading accuracy: 0.1mm

Test Procedure:

1. Place on vibration-free work table, level the instrument

2. Secure coated test panel on the test table

3. Place indentation device vertically on coating surface

4. Remove device after specified time

5. Measure indentation length with reading microscope

6. Calculate indentation resistance from indentation length

Precautions:

• Clean and dry after each use

• Only trained personnel may operate

• Do not leave during testing

• Store in clean, non-corrosive room temperature environment

• Read manual carefully before use

Maintenance:

• Clean promptly after each use

• Regularly verify indentation device accuracy

• Store in dry place when not in use

Available in different specifications: different load specifications (500g, 750g, 1000g, etc.) and different indentation device weights (500g, 1kg, 1.5kg, etc.) to suit various coating types and testing standards.

Mainly used in paint manufacturers, coating contractors, automotive coating industry, furniture manufacturers, quality inspection institutions, research universities, and more for paint film hardness testing.
