Accuracy and Reliability
Despite their compact design, portable hardness testers deliver accurate and reliable measurements. Engineered for durability in harsh conditions, these instruments ensure consistent performance, safeguarding the integrity of the materials under examination.Types of Portable Hardness Testers
Ultrasonic Contact Impedance (UCI) Testers
Ultrasonic portable hardness testers utilize the ultrasonic contact impedance (UCI) method. This technique involves applying a vibrating rod with a diamond tip to the surface of the material under investigation. The change in impedance resulting from the indentation is subsequently used to calculate the material's hardness. UCI testers are particularly advantageous for assessing thin materials, coatings, and small components.Applications:
- Thin materials
- Hard-to-reach areas
- Coatings and surface treatments
Leeb (Dynamic) Testers
Leeb hardness testers operate on the principle of measuring rebound. In this method, a test tip is propelled against the material, and the velocity of the rebound is recorded. The hardness of the material is then determined by calculating the ratio of the rebound velocity to the impact velocity. These testers are particularly well-suited for assessing large and heavy components, providing accurate and reliable results in industrial applications.Applications:
- Large, heavy objects
- Castings and forgings
- Weld inspections
Combined (Leeb + Ultrasonic) Testers
Combined testers offer the advantage of utilizing both UCI and Leeb methods. This enables users to select the most appropriate testing technique according to the specific material and application requirements. This dual functionality enhances their adaptability to a diverse range of testing needs.Applications:
- Versatile environments
- Mixed material types
- Comprehensive testing requirements
