Why Choose the Lovato DMK16R1 Three-Phase Digital Multimeter?
The Lovato DMK16R1 is a comprehensive three-phase digital multimeter and energy monitoring instrument designed for electrical switchboards, machinery panels and industrial power distribution systems. It combines voltage, current, frequency, power factor, active power, reactive power, apparent power and energy measurement within one compact panel-mounted device.
The instrument uses True RMS measurement for voltage and current, helping deliver dependable readings where electrical waveforms contain harmonics or distortion. It provides individual measurements for each phase alongside total three-phase power values, enabling engineers to assess system performance, identify phase imbalance and monitor electrical demand.
The DMK16R1 also includes active and reactive energy counters, an operating-hour counter and a programmable relay output for alarm, control or protection functions. Its compact 96 × 48 mm flush-mounted format, removable terminals and IP54 front protection make it well suited to professional panel-building and energy-management applications.
