Siglent SDM3055 5 1/2 Digits Dual-Display Digital Multimeter
The Siglent SDM3055 is the workhorse of the SDM3000X family — the resolution point where a multimeter stops being a checker and becomes a measurement tool. With 240,000 counts and 0.015% basic DCV accuracy it resolves the differences that matter in development work: a regulator that sits at 3.298 V instead of 3.30 V, a shunt reading a few milliohms high, a sensor drifting microvolt by microvolt. True-RMS AC, 2/4-wire resistance, capacitance, frequency and TC/RTD temperature complete the function set, all on the 4.3-inch dual display.
SDM3055 — 5½ digit bench multimeter
The SDM3055 is the all-rounder of the family: 5½ digits and 240,000 counts with 0.015% basic DCV accuracy, True-RMS, and a 4.3-inch dual display that shows two measurements at once — frequency behind a voltage, ripple behind a DC level. USB and LAN with SCPI make it automation-ready out of the box.

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.

Accessories & related
Need multi-point scanning? The SDM3055-SC adds the factory-installed 12-channel SC1016 scanner card for €698.00.
Spare pair of 1000 V CAT III multimeter test leads.
Add GPIB (IEEE-488) control for ATE integration.
The same meter with the SC1016 12-channel scanner card factory-installed — scanning is not a field upgrade, so choose -SC if you may ever need it.
