ЭЭ8003.2

 Experience, quality, reliability

Meter is applied to measure watt-hour energy usage in single-phase circuit of alternating-current on one, two, three or four tariffs at eight time zones on objects of industrial enterprises, electric-power industry and agricultural sector as well as domestic household.

Meter can be used for multiply-tariff electric energy account  both independent and as part of automated system of control and electric energy account.

Meter is connected proximate to AC network in enclosed spaces.

Meter is included to the State register of measuring instrument of the Republic of Belarus and the Russian Federation.
