| | XCHL-11A/XCHL-11B Leeb Hardness Tester Detailed Information: |
The XCHL-11A and XCHL-11B multifunctional Leeb hardness tester is a new handheld, multifunctional dynamic hardness testing instrument designed with the latest advanced microprocessor technology. It features high testing accuracy, stable and reliable performance, compact size, easy operation, portability, and a wide measurement range. It is suitable for rapid hardness testing of metal materials, especially for on-site hardness testing of large components and non-removable parts. It can automatically convert the measured Leeb hardness values into Brinell, Rockwell, Shore, and other hardness values based on different materials and directions, and print records. It is an ideal hardness testing instrument for use in industries such as molds, machinery, machine tools, hardware, heat treatment, forging, and special steel.

II. Main Applications
1. Hardness testing of products in mass production;
2. On-site hardness testing of permanently assembled mechanical components after installation;
3. Hardness testing of heavy workpieces;
4. Hardness testing of mold cavities;
5. Hardness testing in narrow spaces of mechanical components;
6. Failure analysis of equipment;
7. Differentiation of metal materials in warehouses;
8. Hardness control testing for heat treatments such as annealing, tempering, and quenching.
III. Main Technical Parameters:
Measurement Accuracy: Measurement error less than or equal to ±6HLD (HLD=800);
Operating Temperature: 0-40℃;
Operating Voltage: 4.6V-6.0V
Maximum Dimensions: 223＊91＊40mm

4. Select test direction and test material via keyboard;
5. Can be configured with seven different types of impact devices (probes) (D, DC, E, D+15, DL, C, G);
6. Turn the backlight on or off at any time during testing;
7. Full-screen large font display of current test status and measurement results;
8. After shutdown, remembers the last set of test results and all pre-set parameters.
V. Impact Device (Probe) Introduction
1. Impact Device D
Universal standard configuration, used for most hardness measurements. Weight: 75g
2. Impact Device DC
The impact device is particularly short and uses a special loading rod for loading; otherwise, it is the same as the D-type. Used in very confined spaces, such as inside holes, cylinders, or within assembled machinery. Weight: 50g
3. Impact Device D+15
Smaller head. Used for hardness measurements in grooves or recessed surfaces. Weight: 80g.
4. Impact Device E
Diamond impact ball head (approx. 5000HV). Used for measuring very high hardness (typically above 50HRC/650HV), tool steel with high carbide content, and hardness up to 1200HV. Weight: 80g.
5. Impact Device C
Impact energy is about one-quarter of the D-type. Used for surface-hardened components, surface coatings, thin-walled, or impact-sensitive components. Weight: 75g
6. Impact Device G
Larger impact ball head, increased impact energy, lower requirements for surface finish. Only used for hardness measurements in the Brinell hardness range up to 650HB. Weight: 250g
7. Impact Device DL
Exceptionally small head. Used for hardness measurements in very narrow grooves or recessed surfaces. Weight: 80g.
