The main purpose
Mainly used to test the high-speed particle impact resistance of personal eye protection.
Instrument structure
It is mainly composed of a steel ball launching device, a steel ball speed detection device, and a two-dimensional mobile alignment device for eye protection.
Instrument characteristics
The launch speed of the steel ball of this equipment is adjustable, which can meet the requirements of the standard for different launch speeds. The speed measurement signal waveform is visible, and the operation of the instrument is safe, convenient and intuitive.
