High Voltage Meter
DU-3900 - Delta United Instrument Co., Ltd. (DUI)
The DU-3900 is a digital voltmeter that can measure high voltages up to a 10kV AC and DC at high accuracy. Its high input impedance (1000M) makes it suitable for measurement of high impedance voltage circuits. Since it has a high accuracy despite its small size and light weight, it can also beeasily used as a portable calibrator.
