8588A Reference Multimeter

Accurate data, delivered amazingly fast

Shorter test time on the 8588A/8558A high-speed digital platform enables you to increase throughput, improve yield and realize a greater return on your investment. The 8588A/8558A digitizes to memory at 200 nanoseconds per reading and delivers 4.5 digit data to a PC via USB, Ethernet and GPIB at 100,000 readings per second. Fast, high resolution data capture gives you the quantity and quality of information you need to make timely, correct decisions affecting system throughput and efficiency.

Product Description

The 8588A Reference Multimeter is the world’s most stable digitizing multimeter. Designed for calibration laboratories, this long-scale high-precision reference features superior accuracy and long-term stability over a wide measurement range, with an intuitive user interface and a color display.

The 8588A delivers reliable and reproducible measurements with exceptional performance suitable for primary level laboratories. With more than 12 measurement functions, including the new digitize voltage, digitize current, capacitance, RF power, and external shunts for dc and ac current, the 8588A helps you consolidate your lab’s cost of test into a single measurement instrument. Its superb analog performance is augmented by Fluke Calibration’s new high-speed system design and the industry’s fastest direct digitizing capability, enabling significant throughput increase for many automated systems demanding a combination of the highest speed and best accuracy.

The 8588A holds the industry’s best one-year dc voltage accuracy of 2.7 uV/V at 95 % confidence interval, or 3.5 uV /V at 99 %, and best 24-hour stability of 0.5 uV/V (95 %) or 0.65 uV/V (99 %), enabling it to outperform other long-scale reference multimeters on the market. The 8588A further pushes the speed envelope by producing a stable 8.5 digits reading in a mere one second.

The 8588A platform consists of two models:

  • The 8588A Reference Multimeter is designed for calibration and metrology laboratories that require the highest stability for the most accurate measurements to maintain maximum confidence in traceability

Each model features a common intuitive user interface with an easy-to-navigate menu structure for all configuration and matching SCPI-compliant commands for an automated environment. In addition, both models support a minimum of 100,000 readings per second at 4.5 digits across GPIB, USB or Ethernet.
