Advantages
 
Pen Type Leeb Hardness Tester

1. Wide measuring range. Based on the principle of Leeb hardness testing theory. It can measure the Leeb hardness of all metallic materials.


2. Large screen(128×64 dot matrix LCD), showing all functions and parameters.


3. Test at any angle, even upside down.


4. Direct display of hardness scales HRB, HRC, HV, HB, HS, HL.


5. Seven impact devices are available for special application. Automatically identify the type of impact devices.


6. Large capacity memory could store 500 groups (Relative to average times32~1 ) information including single measured value, mean value, testing date, impact direction, impact times, material and hardness scale etc.


7. Upper and lower limit can be preset. It will alarm automatically when the result value exceeding the limit.

8. Battery information indicates the rest capacity of the battery and the charge status.


9. User calibration function.


10. Software to connect with PC via USB port.


11. With EL background light.


12. Thermal printer integrated, convenient for in field printing.


13. NI-MH rechargeable battery as the power source. Charge circuit integrated inside the instrument. Continuous working period of no less than 150 hours (EL off and no printing).


14. Auto power off to save energy.

The Statistical Parameters Used For Processing Measurements

1. Maximum, minimum, and mean values.


2. Standard deviation from the mean.


3. Average deviation from user-set values.


4. Number of results outside the upper/lower limit range specified by the user.


5. Maximum deviation from the upper/lower border.


6. Automatic elimination of erroneous results.


7. Comparison of measurement results in series using comparison charts displayed on the hardness tester.

 

There are two types of Leeb hardness testers such as bench (stationary, classical) as well as portable (mobile, electronic)

 

Bench hardness tester

This bench hardness tester is a traditional type used to determine the hardness of a sample employing the standard methods of Rockwell, Vickers, Brinell, or Shor. Hence, they can be called ‘bench Rockwell hardness tester’ or ‘bench Brinell hardness tester’. There are many other bench hardness testers used to measure the hardness of the sample not only using just one scale but varied hardness scales.

Portable hardness testers

Unlike the bench testers, portable hardness testers are smaller in size with lightweight. These testers are compact in nature, which determines the hardness using various hardness scales. Moreover, the modern portable hardness testers can detect the hardness by employing all hardness scales. Its major advantages include user convenience as well as portability.

Scales And Materials

 

 

The device comes with preliminary calibrations for various scales and materials, which makes the device universal.

SCALES: HRC, HRB, HB, HV, HL, MPa.

MATERIALS: Steel, alloy steel, cast iron, stainless steel, aluminum, bronze, brass, copper.

It also can be calibrated for any scale and materials (USER scale).
