Siglent SDM3045X 4 1/2 Digits Dual-Display Digital Multimeter
The Siglent SDM3045X is the proof that a real bench multimeter no longer needs a mid-range budget. For the price of a good handheld you get 60,000 counts on a 4.3-inch dual display, True-RMS AC measurement, and the complete bench function set: DC and AC voltage and current, two- and four-wire resistance, capacitance, frequency, continuity, diode test and thermocouple temperature. The dual display earns its keep daily — watch a DC level and its AC ripple, or a voltage and its frequency, without switching modes.
SDM3045X — 4½ digit bench multimeter
The SDM3045X is the affordable route to a true bench multimeter: 4½ digits, 60,000 counts and True-RMS AC on a bright dual display. It replaces a drawer full of handhelds with lab-grade repeatability, a full function set and USB remote control.

More than the numbers
Dual display, full function set
Show two readings of one signal at once — DC level with AC ripple, voltage with frequency. True-RMS AC, 2/4-wire resistance, capacitance, temperature and more are all built in.
Analysis on the instrument
Statistics, histogram, trend chart, limit testing and dB/dBm maths run directly on the meter — and EasyDMM on the PC adds configuration, logging and export over USB or LAN.
