Shell Material: Molded clear tempered glass.

Inner Structure: Solar cell panel, PCB, Rechargeable battery, High luminance LED and Magnetic switch

Minimum compressive resistance: 18 metric tons

First, to install the specimen on the tester base. Then, to coincide both the center of the steel bar (min. diameter 25 mm, min. thickness 10 mm) and the convex part of the specimen. At last, to avoid the vibration during the testing process, so increase loading slowly. Impact resistance: no crack or chip may be viewed after ball-impact test hardened-steel Ball (1.0 kg) with a diameter of 63.5 mm means for dropping the ball freely from 1.5 meter height.

Ambient Temperature: - 20°C ~ + 70°C
