Product overview: Fluke 8558A 8.5 Digit Multimeter

The 8558A 8.5 digit multimeter offers 5 mega-samples-per-second high resolution digitizing for system automation in labs and manufacturing test environments.  Fluke’s new high-speed system design and the industry’s fastest direct digitizing capability enable significant throughput increases for many automated system applications that require a combination of highest speed and best accuracy.  The superb accuracy is delivered over a wide measurement range, over nine functions, with an intuitive user interface on a color display.


The 8558A shares the same platform as the fully loaded 8588A Reference Multimeter. The platform features a common intuitive user interface with easy-to-navigate menu structure for all configuration and matching SCPI-compliant commands for automated environment. The 8588A platform guarantees a minimum of 100,000 readings per second at 4.5 digits across GPIB, USBTMC or Ethernet, and an onboard data memory that can hold up to 15 million readings.
