The FR2020B Three-phase Digital Phase Voltammeter by FUZRR Technology is a versatile and intelligent handheld device designed for accurate three-phase power system analysis. It supports direct measurement of AC voltage, current, phase angles between voltages and currents, frequency, active power, reactive power, apparent power, and power factor. With additional functions such as transformer wiring group identification, inductive/capacitive circuit detection, and energy meter wiring verification, it is a critical tool for maintenance, inspection, and diagnostics in power utilities, industries, and laboratories. The FR2020B features a large-caliber 50mm clamp, color LCD display, 400-group data storage, USB data upload, and a robust silicone protective cover, offering reliability and portability for field operations.
