Đồng hồ đo điện và công suất Contrel EMM-R4h
The digital multifunction meters of the EMM series allow the measure of the main electrical parameters of the electrical energy distribution networks. The local visualisation of more than 30 measured parameters is made with the usage of 4 red LED displays, in order to guarantee a reading clear and simultaneous of different measures. Intuitive selection of measures, that have to be visualised with a LED signal, completes a very simple frontal panel, but also supplies a lot of information.
