Fluke/Philips-Reference Multimeter (Model 8508A)

The Fluke 8508A is an 8.5-digit resolution instrument designed specifically for metrologists. With superior accuracy and stability over a wide range of measurements the 8508A is designed to serve as a versatile precision measurement tool for calibration laboratories that must meet increasingly stringent measurement uncertainty analysis requirements demanded by ISO 17025, as well as the need for increased productivity.

Superior performance and accuracy… with outstanding stability

The 8508A features 8.5 digit resolution, exceptional linearity and extraordinarily low noise and stability, producing what are arguably the most accurate measurements to be had from any commercially available product today. But that’s only part of the story. Measurements must be repeatable today, tomorrow, next week, even next year. That’s why stability must be treated with the same priority as accuracy. The 8508A demonstrates 365 day stability as low as 2.7 ppm, with a 24 hour stability of 0.5 ppm, ensuring that confidence in today’s measurement can be the same as it was yesterday or last year.

Increased functionality and versatility

Metrologists need to make many diverse measurements as part of their complex duties. To achieve this frequently requires a complex array of instruments. The Fluke 8508A provides an extraordinarily broad range of measurement capability. This means you can undertake a wider range of applications, and perform most of your measurement requirements with a single instrument, providing real economies in time and money.

Easy to use

Human error and misunderstanding of measurement setups often have severe impact on measurement accuracy. Such errors are often due to impenetrable or complex user interfaces and lack of user familiarity. The Fluke 8508A’s clear control structure with Dual ParamatrixTM displays and context sensitive menus provides a transparent, logical and intuitive mechanism with which to interact with the instrument. Consistent with the philosophy of designing a product specifically for metrologists, the command and menu configuration is constructed to ensure rapid, error free access to complex measurement setups. It means that you can focus on getting the best possible results, without needing complex sequential or multi-instrument setups, or the need to perform complex mental arithmetic or math to achieve the desired result.

A multiple-measurement workhorse

The robust characteristics of the Fluke 8508A permit replacement of eight other measurement devices by one multi-measurement precision unit. The replaceable devices are:

Current measurements

The 8508A features a remarkable new current measurement system. For the first time, resistance at the input is virtually zero. This means that measurements can be much less invasive, and present virtually zero burden to the measurement points. It also offers the advantage that complex guarding schemes are now largely unnecessary, and measurements can be made more reliably, more repeatably and with greater confidence. Ranges from 200 µA to 20 A and frequencies from 1 Hz to 100 kHz, again ensure that all of your measurement needs are covered including the high currents encountered when calibrating multi-function calibrators.
