Description


Siglent SDM4065A Digital Multimeter

The SDM4065A series is a flagship digital multimeter, providing 6½-digit high accuracy and a maximum reading rate of up to 50,000 times/second, ensuring fast and accurate measurements. Built-in thermocouple cold-end compensation supports a variety of data visualisation functions such as histograms and trend charts, allowing users to analyse data intuitively. USB Device, USB Host and LAN interfaces are standard, supporting remote control and data transmission. Its 2Gb large-capacity storage can save a large amount of measurement data and setting files, making it an ideal choice for professional engineers and researchers.

Key Features:
