Main technical parameters:

1. Steel ball: quality 0.86g; Diameter 6.0mm;

2. Impact speed:

2.1 Low speed impact (L): 45+1.50 m/s;

2.2 Medium speed impact (M): 120+30 m/s;

2.3 High speed impact (H): 190+50 m/s;

3. Test purpose: Use (1/4 "(6mm) steel balls to test the lens strength of glasses (especially protective lenses), as well as impact resistance tests such as welding points, frame and lens fit;

4. Test distance (from emission port to test specimen): 200mm laser positioning indicator;

5. The control panel has an emergency stop device for higher safety; Digital LCD display, displaying the velocity of the emitted material (m/s);

6. The test bench has adjustable devices. Easy to install helmets quickly and conveniently;

7. The high-speed steel ball speed measurement system adopts advanced high-precision laser speed measurement monitor;

8. The normal operation of the machine requires connection with an air compressor. Provide high-pressure gas source combined with high-precision gas valve to enable the steel ball to instantly reach the testing speed;

9. Equipped with a safety alarm display light, the equipment cannot enter the testing state when the door and steel ball valve of the equipment are not closed properly;

10. This instrument is operated by air, with a fully enclosed testing space and an observation port installed on the door;

11. Instrument power supply: AC220V ± 20%.
