Electrostatic discharge between human body and a metal object or between metal objects can reach up to thousands of volts, which may cause malefactions or damages to connected electrical equipment and devices.
The EDS 20H is the state-of-art handheld ESD generator, and the first of its kind independently researched and developed in China. It is designed according to IEC/EN 61000-4-2 with ergonomic design, integration design, battery powered and mains powered via an adaptor. It boasts easy touch screen operation, safe operation with temperature and humidity monitoring, and stable operation suitable from different testing occasions.
