ETCR4400 Multifunction Three-Phase Phase Voltammeter is a multi-function meter equip with touch screen, which can measure voltage amplitude, current amplitude, voltage phase, current phase, frequency, power, active power, reactive power, harmonics, and It can display the vector diagram of three-phase voltage and three-phase current in real time. In addition, it can also judge the three-phase phase sequence, inductive and capacitive circuits, test the secondary circuit and check whether the wiring of the watt-hour meter is correct or not, and repair the line equipment device etc. This product is simple to operate, easy to use, fast, stable and reliable in measurement. Widely used in electric power, petrochemical, metallurgy, railway, meteorology and other units.

ETCR4400 Multifunction Three-Phase Phase Voltammeter consists of the host, current clamps, and voltage test lines. It equip with 5-inch touch color screen, Chinese interface, direct function, automatic measurement, easy and fast operation, accurate and reliable. At the same time, the instrument adopts large-capacity rechargeable lithium battery, and has functions such as data storage, data review, automatic shutdown, and USB data upload and export. Because the instrument adopts a special metering chip, the instrument has very high-precision electrical parameter measurement, can display the changes of the parameters to be measured in real time, and has the function of saving data with one key.
