1、 Product Overview

BR-R5000Electric quantity recorderIt can directly measure electrical parameters such as voltage, current (true effective value), active power, reactive power, power factor, frequency, and electricity in single-phase AC circuits; Simultaneously record voltage, current, and battery level. Can generate various electricity reports; Current, voltage historical data, and power consumption reports can be transmitted to the upper computer through a USB interface for storage and analysis; Instruments have functions such as current and voltage over limit alarm, remote data transmission, and electric energy surge output. They are widely used in industries such as environmental protection, metallurgy, petrochemicals, and steel to monitor the current and power consumption of large equipment driven by motors, as well as the measurement and monitoring of single-phase electric energy in distribution networks and enterprises.
