Why Choose the Lovato DMG110 Modular Digital Multimeter?
The Lovato DMG110 is a professional three-phase digital multimeter designed for comprehensive electrical monitoring in industrial switchboards, commercial distribution panels and automation systems. As part of the Lovato DMG measurement instrument range, it combines high-accuracy True RMS measurements with an integrated RS485 communication interface, making it ideal for local monitoring and remote energy management.
Suitable for single-phase, two-phase and three-phase systems with or without a neutral conductor, the DMG110 measures voltage, current, active power, reactive power, apparent power, power factor, frequency and energy consumption. It also provides voltage and current harmonic analysis up to the 15th harmonic order, helping engineers identify power quality issues and optimise electrical system performance.
Designed for use with external current transformers having a 1 A or 5 A secondary output, the DMG110 features a wide-range 100-240 V AC or 115-250 V DC auxiliary supply, a multilingual backlit LCD display and integrated RS485 Modbus RTU/ASCII communication, providing seamless integration with PLCs, SCADA systems and building management platforms.
