Fluke 8508A 8½ Digit Multimeter
Introduction to the Fluke 8508A:
The FLUKE 8508A is a digital multimeter with 8 ? resolution designed for metrology scientists. It has a wide measurement range, ultra-high accuracy and stability, and is an essential basic instrument for calibration laboratories. It can meet the strict uncertainty analysis requirements of ISO17025 and other metrological verification requirements.

The DC voltage and AC voltage measurement ranges of FLUKE8508A are from 200mV to 1kV, covering all your voltage measurement needs. Full 8.5-bit resolution is available on all ranges, giving resolutions down to 1nV. Its AC measurement bandwidth extends to 1MHz. Combining its excellent linearity and ratiometric measurement capabilities, the FLUKE8508A can replace Kelvin-Valley voltage dividers and AC/DC voltage transfer standards. Therefore, a single instrument can realize solutions for multiple applications, which greatly improves your work efficiency.
The FLUKE 8508A current measurement features a prominent new current measurement system. For the first time, it achieves virtual zero ohm resistance at the current input. This means that the influence of the measuring instrument on the circuit is greatly reduced and practically zero load is present at the measuring point. The 8508A's current measurement capability has another advantage, making the traditional complex shielding protection schemes in current measurement unnecessary, making measurements more reliable, repeatable, and with a higher degree of confidence.
The 8508A current measurement range is from 200mA to 20A, and the frequency range is from 1Hz to 100kHz, which is guaranteed to meet all your measurement needs, especially the high current measurement needs when calibrating multi-function calibrators.
*The resistance measurement range is from 2W to 20GW, and the resolution is up to 10nW. It is a complete resistance measurement system. In addition, this instrument also has a high associated voltage of 200V and a large measurement current of 100mA.
* To further expand the scope of measurement work, 8508A also provides 2, 3, 4-wire platinum resistance PRT or standard platinum resistance SPRT temperature measurement capability, temperature measurement range from -200 degree to 660 degree . With the ability to give simultaneous temperature and resistance readings and the ability to linearize the ITS-90 and Callendar van Duesen equations, the 8508A is an ideal tool for both temperature measurement and platinum resistance PRT calibration work. As with resistance measurements, current reversal techniques are used in temperature measurements to eliminate thermoelectric potential errors.
* This greater flexibility expands the scope of precision measurement work. And using the 8508A will get better uncertainty.
The Fluke 8508A features dual-channel ratiometric measurement for easy and fast delivery of measurement capabilities. For example, the excellent performance of this resistance measurement system is not only reflected in its technical indicators, but also in Fluke's attention to measurement technology. When making a ratio measurement, the same current is forced through both resistors and only the measurement circuit is switched. During resistance measurements, the measurement current can be reversed to eliminate errors caused by thermoelectric effects.
* Fluke Corporation's Extended Range Metal Sheathed Standard Platinum Resistance Thermometer 8508A-SPRT and Secondary Standard Platinum Resistance Thermometer 8508A-PRT Standard Metrology Engineers designed and manufactured to extend the precision platinum resistance temperature measurement of the Fluke Corporation 8508A Reference Digital Multimeter Function.
