One Product Name: Plastic Ball Indentation Hardness Tester

Two Product Model: HQY-96

III. Overview:

  Our company's自主研发HQY-96 Plastic Ball Indentation Hardness Tester, featuring automatic loading, timing selection, deformation collection methods, and replacing the commonly used digital block display with a touchscreen color display in Chinese characters. This allows operators to perform test operations based on the Chinese character prompts on the LCD screen after startup, facilitating user operation. The parameters of the Plastic Ball Indentation Hardness Tester comply with the provisions of relevant standards such as GB3398.1-08 Plastic Hardness Test, Part 1: Ball Indentation Method, and ISO 2039-1-2001 Plastic Hardness Test, Part 1: Ball Indentation Method.

    

Ball Indentation Hardness Tester Features:

1. This instrument employs microprocessor control and integrated, digital measurement technology. It is programmed according to the standard test procedure.

2. Color crystal display, touch screen operation, easy to use and understand.

3. Features a digital micrometer, force measurement system, high measuring accuracy, and stable control.

4. Data printing with a mini printer.

5. This instrument has been upgraded to a touchscreen control, featuring a novel approach, easy operation, and user-friendly design.

6. Replaced the original monochrome LCD screen with a large 65535-color screen, offering improved visual effects and more displayed information on the interface.

7. Enhanced the calculation feature of test results, retaining decimals and rounding off to the nearest whole number for increased accuracy.

8. Various parameter settings are adjustable to accommodate the operational flexibility of experimenters, meeting diverse testing requirements.

9. Any step in the testing process can be manually skipped for convenience.

(English operation methods can be customized to meet specific customer requirements.)

Four Working Principle:

    HQY-96 Plastic Ball Indentation Hardness Tester, according to the relevant requirements of the standard, measures the average pressure on the unit indentation area after the indentation head (mounted with a specified diameter steel ball) is vertically pressed into the sample surface under a given test load by the loading device, and held for a certain period of time. The pressure is expressed in kgf/mm² or N/mm².

The ball indentation hardness value is calculated according to the following formula:

       0．21P

H=------------------------

     25πD（h-0.04）

In the formula:H - Ball indentation hardness, kgf/mm² or N/mm²

      P – Test Load, kgf or N

      D—Steel ball diameter, mm

      h -痕深 after frame correction, mm.

Note:h=h1-h2;

    H1 - Depth under test load, mm

    h2——Frame deformation under test load, mm
