How to Choose the Best Surface & Hardness Testing
Key Features to Consider
Look for testers with digital displays for easy reading of results. Features like data logging capabilities can be beneficial for record-keeping and analysis. Ensure the device comes with traceable calibration certificates to guarantee accuracy. If portability is important, consider battery life and ruggedness for field applications.
Frequently Asked Questions
What is the difference between Shore A and Shore D durometers?
Shore A is designed for softer materials like rubber and flexible plastics, while Shore D is used for harder materials such as rigid plastics and hard rubber. The durometer scale provides a relative measure of hardness.
Can I use a hardness tester on non-metallic materials?
Yes, depending on the type of tester. Shore durometers are specifically for polymers and elastomers. Vickers testers can also be used for ceramics and other non-metallic substances.
How often should a hardness tester be calibrated?
Calibration frequency depends on usage and industry standards, but typically it's recommended annually. Frequent or heavy use may necessitate more frequent checks to ensure accuracy.
What is an indentation test?
An indentation test measures a material's resistance to permanent deformation. A standardized indenter is pressed into the material's surface with a specific force, and the resulting indentation is measured.
Are portable hardness testers as accurate as benchtop models?
Modern portable testers offer excellent accuracy for many applications. However, benchtop models often provide higher precision and repeatability, especially for critical measurements or research.
