Highlights
1. Direct display of measured value
2. High accuracy
3. Maximum and average value functions
4. Easy-to-read backlit LCD screen
5. Power-saving automatic shutdown
6. Wide measuring range
7. One-handed operation
Test Procedure
The specimen is placed under the indentor of the Barcol hardness tester and a uniform pressure is applied to the specimen until the dial indication reaches a maximum. The depth of the penetration is converted into absolute Barcol numbers.
Applications of Barcol Hardness Testing
Aluminum and Soft Metals
Ideal for aluminum alloys, brass, and copper, ensuring proper hardness for structural applications.
Composites and Fiberglass
Used in the marine, automotive, and aerospace industries to test fiberglass, reinforced plastics, and carbon fiber components.
Plastics and Rubber
Essential for polymeric materials, ensuring consistency in hardness and durability.
Paint and Coatings
Evaluates the hardness of protective coatings applied to different surfaces to ensure wear resistance.

How to Use a Barcol Hardness Tester
Step 1: Surface Preparation
- Ensure the surface is flat, clean, and dry.
- Avoid coatings or dirt that may alter results.
Step 2: Calibration
- Use the provided standard calibration block.
- Adjust the pointer to match the reference value.
Step 3: Take the Measurement
- Firmly press the tester perpendicular to the surface.
- Read the value from the dial or digital display.
- Repeat 3–5 times and calculate the average.
Step 4: Record and Interpret
- Use hardness tables or comparison charts if needed.
- Document results for quality control.
Limitations and Considerations
Surface Curvature
Not ideal for very small or curved samples.
Material Thickness
Recommended minimum is ~1.5 mm.
Surface Flatness
Irregularities can affect accuracy.
No direct conversion to Rockwell or Brinell
Must use comparison tables.
