The ECS trademark

ECS is certified to Directive 2014/32/EU on Measuring Instruments (MID). This Directive covers ten categories of measuring instruments and is designed to harmonise the requirements for new measuring instruments placed on the market or put into use in Europe by eliminating the regulatory differences at national level which currently hinder trade. All ECS Energy Meters are available either in non-MID or in MID versions.
