1MID certified high-precision electric meter

The MID certification of the electricity meter marks that it has successfully passed the strict certification process of the EU Measuring Instruments Directive (MID). As a mandatory certification system for measuring instruments implemented by the European Union, MID certification aims to ensure that measuring instruments in the EU market meet uniform high standards, effectively protecting the legitimate rights and interests of consumers and further promoting trade liberalization and facilitation.MID certified electric meter

In order to regulate the market for measuring instruments and eliminate technical barriers among member states, the European Union officially issued the MID Directive in 2004 (initially Directive No. 2004/22/EC), which was fully enforced on October 30, 2006. The core mission of MID certification is to ensure that every measuring instrument has a high degree of accuracy, reliability, and compliance, to create a fair and unified market competition environment for manufacturers, and to build a solid protection barrier for consumers' interests.
