Features
 
Rebound Hardness Tester

1. LCD display of 128×64 matrix is used.

 

2. Using the D high precision impact device

 

3. Converts to all common hardness scales(HV ,HB,HRC,HRB,HRA,HS).

 

4. English displaying and menu operating, the operation is easy and convenient.

 

5. Hermetically sealed metal shell, solid and durable, has excellent resistance to vibration, shock and electromagnetic interference ability.

 

6. With USB2.0 interface, multiple communication modes are adopted to meet customized requirements of various users.

 

7. Equipped with a data processing software, through the USB interface, can exchange data with computer printing and parameter setting

 

8. Equipped with 7 types of impact devices which need not to be recalibrated when changing them, the system can identify the type of impact device automatically.

 

9. Max 600 groups（impact times:32～1）of data can be stored at internal non volatile data storage.

10. Upper and lower limit of hardness can be preset; When the tested value exceeds the limits, alarm will send out automatically to make convenient for the requirements of batch measurements. Back light display has been used to make convenient for the use in poor light.

 

11. Test values software calibration function.

 

12. Material of “cast steel” is added; HB values can be read out directly when D/DC impact device is used to measure “cast steel” work piece.

 

13. Printer be separated from main unit and copies of testing results can be printed as required.

 

14. Power is two of AA battery. Continuous working period: approx. 200 h (no back light on).

 

15. Software of PC can be installed according to the requirements of user, the function will be more powerful to satisfy the more strict demands of quality control and management

 

16. Failure analysis of pressure vessel, steam turbo-generator set and other equipment

 

17. Narrow testing space where work piece installed

Metal Shell Hardness Tester

 

The three main types of hardness tests are
 

Rockwell Hardness Test

Measures the depth of penetration under a large load.

Brinell Hardness Test

Uses a hardened steel or carbide ball to create an indentation on the material’s surface.

Vickers Hardness Test

Utilizes a diamond pyramid indenter for precise hardness measurements, especially for thin materials.

 

Hardness Tester Key Components

 

Metallic Hardness Tester Durometer

Indenter

A specifically shaped object (e.g. ball, cone, or pyramid) made of a very hard material like diamond or hardened steel.

Color Screen Display Hardness Tester

Force application mechanism

Applies a precise, controlled force to the indenter. This can use weights, springs, or closed-loop control systems.

Leeb Hardness Tester with Printer

Measurement system

Measures the size or depth of the indentation, either optically or through depth sensing.

 

Main Application
 

1) Die cavity of molds


2) Bearings and other parts


3) Failure analysis of pressure vessel, steam generator and other equipment


4) Heavy work piece


5) The installed machinery and permanently assembled parts.


6) Testing surface of a small hollow space


7) Material identification in the warehouse of metallic materials


8) Rapid testing in large range and multi-measuring areas for large-scale work piece

Working Principle

 

3 Years Warranty Metal Hardness Tester

1. Place the sample to be tested on the test bench and secure it.

 

2. Select the appropriate test load and test tip type (e.g. drill).

 

3. By manual or automatic operation, the test needle is applied to the sample surface.

 

4. Observe the size of the indentation left by the test needle on the sample surface or perform rebound measurements.

 

5. Based on the measurement results and corresponding standards, the hardness value of the sample is determined.
