Digital Multimeters Siglent SDM4065A-SC

Product Overview SDM4065A-SC

In the automatic production lines where speed drives profitability, the digital multimeter as core equipment in automated testing directly impacts system efficiency. On April 16, 2025, Siglent launches the SDM4000A series high-speed 5½-digit and 6½-digit digital multimeters. With fast reading rate of 50,000 readings/s, minimum sampling interval of 20 µs, 11 measurement functions, and a touchscreen with intuitive interface, the SDM4000A not only elevates individual product testing efficiency but also enhances overall production line performance in accuracy-driven automated environments.

True 5½-digit and 6½-digit precision

SDM4000A Series offers 5½-digit (220,000 counts) and 6½-digit resolution (2,200,000 counts) with a full-scale display range from -2,199,999 to +2,199,999. Its exceptional performance ensures precise capture of subtle current variations and large voltage fluctuations

High speed Measurement 

The SDM4055A series achieves a maximum reading rate of 4,800 readings/s, while the SDM4065A series supports up to 50,000 readings/s. Both models offer adjustable measurement speeds (fast/medium/slow). For the SDM4065A, its sampling interval can be precisely configured from 0.001 PLC to 1,000 PLC (Power Line Cycle), enabling superior performance in high-speed data acquisition and micro-variation monitoring—ideal for applications requiring precise measurements.
