Shop onlineHardness Testers
Improved mechanical resistance is part of many quality requirements. One important criteria for assessing this feature is hardness. Depending on the requirements there are various Hardness Testers to choose from. Some are dedicated to characterise coatings and others are more suitable for testing bulk materials such as metals, plastics, rubber or elastomers. Elcometer manufacture and supply a wide range of instrumentation designed for the hardness tests most frequently used in the industry - these include pendulum, scratching, indentation or rebound measuring methods. Scratch Resistance: To assess a coating's resistance to scratch there are a number of different instruments that can be used: Pencil Hardness Tester (Wolff-Wilborn), Sclerometer, Clemen Apparatus, Scratching and Shearing Instrument. Resistance to Indentation: There are many instruments available to assess the resistance to penetration. For coatings in particular, there are three common methods where the depth of penetration of a weighted tool is used to show the coating's resistance to penetration: Buchholz, Barcol, Shore.
Frequently asked questions
What is a Hardness Tester?
A hardness tester is a device used to measure the hardness of a material, which indicates its resistance to deformation, indentation, or scratching.
How does a Hardness Tester work?
Hardness testers typically apply a load to a material's surface using a specialized tool and measure the depth or size of the indentation left behind.
What materials can be tested with Hardness Testers?
Hardness testers can be used on various materials, including metals, plastics, rubber, and coatings.
What are the different types of Hardness Testers?
The different types include pendulum, scratching, indentation, and rebound measuring methods.
How do I choose the right Hardness Tester?
Choosing the right hardness tester depends on the material type, the required measurement technique, and the accuracy needed.
