Счетчики Альфа A1800

Новые микропроцессорные счетчики Альфа А1800 производятся на заводе Эльстер Метроника в Москве, представляют собой усовершенствованную модификацию приборов учета Альфа, Альфа Плюс и ЕвроАЛЬФА с классом точности 0.1S, 0.2S, 0.5S и 1. Оборудование прошло необходимые испытания, поэтому включено в реестр средств измерений РФ.
