The ND20 meter is a digital programmable panel meter destined for the measurement of single-phase power network parameters (2-wire network) and 3-phase, 3,4-wire network in balanced and unbalanced systems with the simultaneous display of measured quantities on a LCD display. The meter enables the control and optimization of power electronics devices, systems and industrial installation operations.

ND20儀表是一種數字式可編程面板儀表，用于測量單相電網參數(2線網)和3相、3、4線網絡在平衡和不平衡的系統中，同時在液晶顯示器上顯示測量的數量。該儀表能夠控制和優化電力電子設備、系統和工業安裝操作。
