Product Information
The Rotek 800A Precision Wattmeter Calibrator is a high-accuracy AC power and energy meter calibrator designed for calibrating wattmeters, watt-hour meters, power transducers, and other AC power measurement instruments. It generates precision low-distortion AC voltage and current with adjustable phase angle, allowing accurate simulation of real-world power conditions at various power factors. The 800A is widely used in calibration laboratories, utilities, and electrical test facilities as a transfer standard for power measurements.
