Siglent SDM3055

Digital Multimeter

The Siglent SDM3055 is a high-performance 5½-digit dual-display digital multimeter designed for laboratory, R&D, production test, and calibration environments. It offers a real resolution of 240,000 counts, true-RMS measurement of AC voltage and current, and a read-out speed up to 150 readings per second. The instrument includes a large 4.3″ colour TFT-LCD display (480×272) with advanced visualization features (trend, histogram, bar chart), a 1 GB NAND flash for mass storage of configuration and data files, and communication interfaces (USB device/host, LAN) for remote control via SCPI/USB-TMC. It supports a wide range of measurement functions (DC/AC voltage, DC/AC current, resistance, capacitance, diode/continuity, frequency/period, temperature via TC/RTD), making it a versatile bench instrument. In essence, the SDM3055 combines high-accuracy measurement, fast sampling, advanced data handling and connectivity – suitable for demanding test benches where precision and flexibility matter.
