LBT-ZM-821B Safety Helmet Extreme High-Temperature Pre‑treatment Chamber

It is primarily used to conduct impact and puncture tests on safety helmets after they have undergone pre‑treatment at an extremely high temperature (150°C ± 5°C) for one hour. The testing process operates in fully automatic mode, with the headform automatically entering and exiting the chamber, eliminating the need for manual intervention and thereby preventing potential harm to test personnel caused by the high temperature.
