Surge Protector Device tester

Surge Protector Device tester

Surge protectors are an important safety feature of electrical connections. They guarantee the limitation of voltage peaks that can damage the connected appliances. High-voltage testers verify the correct function of the overvoltage protection and status indicators (LED, sound signaling), electrical strength and measure the leakage current.
