The Rigol DM3068 is a 6.5-digit digital multimeter delivering high-precision measurements across DC voltage, AC voltage, current, resistance, capacitance, frequency, and temperature. Built for research, quality verification, automated production, and education, it combines benchtop operation with remote programming via RS232, USB, LAN, and GPIB interfaces. The instrument performs automatic measurements with integrated math transformations and arbitrary sensor conversion, enabling direct measurement of physical quantities like pressure and flow rate.
