Leeb hardness testers
Rebound (Leeb) testing method
Leeb rebound hardness testers are built for tasks where laboratory benchtop units simply cannot reach. This method is the go-to solution for heavy industrial components: massive forgings, large castings, and thick-walled steel structures. The principle is straightforward — the device measures the energy loss of an impact body as it bounces off the metal surface. This rebound velocity tells you the exact hardness without complex sample preparation.
If you are dealing with solid parts that have a coarse-grained structure, a portable leeb hardness tester is your best option. It handles grey cast iron and structural steels much better than delicate ultrasonic probes.
Practical Use of the Rebound Method
Choosing a portable hardness testing machine saves time during field inspections. You don't have to transport 500kg parts to a lab just to check a weld or a flange. Instead, you get results in seconds. Here is where the Leeb method proves its worth:
-
Large-scale assets: Checking the integrity of installed pipelines, heavy machinery frames, and large shafts.
-
Coarse metals: Getting reliable data on materials where a microscopic Vickers indentation would be too small to represent the overall hardness.
-
Rapid sorting: Inspecting large batches of metal stock or incoming raw materials directly in the warehouse.
Equipment Selection
Reliability in the field depends on the impact device type. Most standard kits include a Type D probe, but for confined spaces or specific alloys, you might need a DC or G impact body. Every portable hardness tester machine in our inventory supports instant conversion between HRC, HB, and HV scales, keeping your quality control compliant with international standards.
Looking for a specific portable hardness tester price? The total cost depends on the configuration and the set of impact devices required for your project. Contact our technical team for an accurate quote and help with selecting the right equipment for your specific metal type.
Accessories
Our comprehensive range of accessories enhances the performance and versatility of our testing equipment. With specialized probes, adapters, and cables, these tools are engineered for high-quality standards, ensuring precise and reliable results across various applications. They extend your equipment's capabilities and support accurate measurements.
Crafted for durability and ease of use, our accessories are designed to meet diverse testing needs. They deliver consistent results across different materials and conditions, optimizing your testing processes and maintaining the integrity of your equipment.
Accessories for Leeb hardness testers
The performance of a Leeb rebound tester often depends on the impact device and support rings used for the job. While a standard probe works for most flat, heavy parts, specific geometries and materials require specialized hardware to ensure the rebound velocity remains accurate.
Impact Devices and Support Rings
We offer a range of interchangeable components to adapt your portable hardness testing machine to different field conditions:
- Alternative Impact Bodies: Choose Type DC for internal surfaces of pipes, or Type G for large, coarse-grained castings that require higher impact energy.
- Support Ring Sets: A set of specialized rings helps stabilize the probe on curved surfaces, such as cylinders or hollow spheres, preventing "wobble" that ruins the data.
Using the right accessories not only protects your sensors from unnecessary wear but also keeps your results consistent with international standards. If you are dealing with complex shapes or restricted access, our engineers can help you select the exact probe configuration for your project.
