The FR2050 Series Flexible Clamp Power Meter from FUZRR Technology is a compact, digital, and multifunctional power meter designed for safe, non-contact measurement of three-phase AC voltage, current, leakage current, phase angle, frequency, power (active, reactive, apparent, total), power factor, and energy. Utilizing advanced Rogowski coil technology, the FR2050 offers high measurement accuracy with strong anti-interference ability, making it ideal for dense wiring environments and narrow spaces. It supports flexible coil sizes (φ150mm or φ300mm), stores 200 groups of data, and features a backlit LCD, automatic shutdown, and low battery prompts. Essential for electrical safety testing, equipment maintenance, and energy audits.
