The outlet is to measure the electric power consumption, and can be an electrical energy-saving evaluation. It has an accuracy of 1.0 (that is in error within ±1%) for any load (resistive capcitive or inductive load). It is the ideal load test evaluation and energy-saving tool both home and office. LCD monitor display the total electricity consumption frame when power on. Plug in /outlet out voltage: 220VAC. Plug in/outlet out operation current or power: 10A or 2.2kW. Start current or power: ≤10mA or 2.2W. Power resolution: 0.01kW. Accurary class: 1.0 class(±1%). Operation temperature: 0-50°C. Anti-submarine dynamic function: yes. History data memory (Memory blackout): yes. Measurement Industry standard: IEC 1036.
