Capable of calibrating all kinds of indicating meters such as DC meters, AC meters, phase meters, frequency meters, power meters, power factor meters, multi-meters, energy meters and electric measurement transducers, etc.
This built-ins are high precision standard sources that respectively relate to voltage, current, phase, power, power factor and harmonic. Capable of outputting standard voltage, current, phase, active power, cross-phase reactive power and true reactive power.
Kingsine's power sources and calibrators are sophisticated tools designed to meet the rigorous demands of a wide range of industries, including the electrical power sector, measurement and quality inspection departments, research institutions, and educational establishments. Their versatility and precision make them indispensable for entities such as Grid Corporation of measurement testing centers, power companies, power plants, national measurement test institutions at all levels, and various industrial sectors like railways, petroleum, chemical industries, and large-scale industrial and mining enterprises. Additionally, they are crucial for meter manufacturers, highlighting their broad applicability.
Kingsine’s power sources and calibrators excel in calibrating a wide array of instruments with remarkable precision. They are capable of calibrating both analog and digital meters, including direct U/I instruments and frequency with DC/AC 0.05% accuracy. This capability extends to a corresponding class of digital multimeters for quality inspection, measurement, and instrumentation maintenance, as well as parts detection. The range of test instruments that can be calibrated includes AC-DC voltage meters, ammeters, single/three-phase active and reactive power meters, phase meters, power factor meters, frequency tables, and synchronized tables, among others.
