Siglent SDM4055A‑SC, 5½‑Digit Touchscreen Bench Digital Multimeter with 16‑Channel Scanner Card

The Siglent SDM4055A‑SC is a high-precision 5½-digit bench multimeter featuring an integrated 16-channel scanner card (SC1016) for automated multi-point measurements. It supports voltage, current, resistance, capacitance, frequency, diode, continuity, and temperature (RTD/thermocouple) measurements. The five-inch capacitive touchscreen displays data in numeric, histogram, trend, and bar formats. Fast sampling at up to 4,800 readings per second, dual-display capability, and advanced math/stat functions make it ideal for R&D, automated testing, and production environments. Connectivity includes USB (Host & Device), LAN (LXI), and optional GPIB; it also supports SCPI commands, VNC, web server access, and EasyDMM-X software. Onboard memory and logging capabilities capture up to 2 million readings and 360 million points to file. The serial scanner provides up to 150 readings per second over all 16 channels.
