Keysight 3458A Digital Multimeter, 8½ Digit Product Description

Keysight 3458A Multimeter shatters long-standing performance barriers of speed and accuracy on the production test floor, in R&D, and in the calibration lab. The Keysight 3458A is simply the fastest, most flexible, and most accurate multimeter ever offered by Keysight Technologies. In your system or on the bench, the Keysight 3458A saves you time and money with unprecedented test system throughput and accuracy, seven function measurement flexibility, and low cost of ownership.

Keysight 3458A Multimeter, recognized the world over as the standard in high performance DMMs, offers very high accuracy and high-speed digitizing for calibration laboratory precision measurements and fast test system throughput.

Select a reading rate of 100,000 readings per second for maximal test throughput. Or achieve highest levels of precision with up to 8-1/2 digits of measurement resolution and 0.1 part per million transfer accuracy. Add this to the Keysight 3458A's simplicity of operation, and you have the ideal multimeter for your most demanding applications.
