The ES9070 is a professional wireless voltmeter for high-voltage transmission line maintenance, eliminating risks from induced voltages. Its detector hangs on live wires (up to 220kV) while the handheld receiver displays real-time readings via 30m wireless transmission. Ideal for power utilities and line inspectors, it combines portability, safety compliance (IEC61010-1), and all-in-one voltage coverage—replacing multiple traditional electroscopes.
