UNI-T UT283A Single Phase Power Quality Analyzer True RMS USB Interface
Features
UT283A power quality Analyzer is a comprehensive analysis, measurement of power quality equipment, which can measure not only the basic electric parameters, harmonics and interharmonics and other basic parameters, it can also capture and record in real time the voltage, current, power failures such as flicker. Also has the support of resistance, capacitance, diode measurement function. Can be used for all kinds of electric power, electrical engineering, communications, medical, energy saving and environmental protection, manufacturing industries and colleges and teaching problems of electric power quality measurement, event logging, and analysis.
