Fluke 164 Hand-Held MultiFunction Counters

Fluke's multifunction counters define a new category of hand-held professional test instruments

This remarkable instrument combines the high accuracy of a top performance counter and a wide-band DVM with a visual waveform display. The multi parameter display shows up to ten different signal parameters simultaneously. The 50 MHz waveform display gives a precise picture of your input signal trigger conditions.

PM 6681 High Performance Timer/Counter

PM 6681: Breakthrough Timer/Counter/Analyzer Performance

With its revolutionary technology, the PM 6681 from Fluke sets the standard for measurement of time intervals, frequency, phase and jitter. PM 6681 is much more than just a timer/counter. Its speed and resolution are comparable to the most accurate time and frequency modulation domain analyzers. Connected to your PC running Fluke's TimeView™ software, PM 6681 fully matches the functionality of a dedicated modulation domain analyzer, at a fraction of the cost.

PM 6681R Rubidium Counter/Calibrator

The highest performance timer/counter/analyzer available

The PM 6681R sets the new standard for measurement and analysis of time intervals, frequency, phase and jitter. For development, calibration, or challenging production test applications, the PM 6681R is the leader.

PM 6685 Universal Frequency Counter

The Fluke PM 6685 Frequency Counter brings calibration lab accuracy to field measurements

The PM 6685 is easy to use, compact, and most important of all, it has today's smartest input triggering for frequency measurements. The battery option for the PM 6685 maintains oven stability for 20 hours, giving you instant oven performance even after long transportation.

PM 6685R Rubidium Counter/Calibrator

Today's most accurate frequency counter

With a built-in Rubidium atomic resonance-controlled frequency reference, the PM 6685R is the most accurate frequency counter on the market and it has the additional benefit of full portability.

High stability, high accuracy and short warm-up time make this instrument ideal for high-accuracy calibration procedures outside the calibration laboratory environment, such as in base station transmitters of large telecommunications networks like GSM.

The short warm-up time makes that the PM 6685R is ready for use quickly, for example after transport or change of location inside a building.

PM 6690 Counter/Timer/Analyzer

The Fluke PM 6690 timer-counter-analyzer is the most versatile and accurate tool for measuring time, frequency, or phase. On top of that, the PM 6690 has built-in analysis capabilities that give you the dynamics and the statistical behavior of the parameter under test. The PM 6690 offers an intuitive user interface and graphical display which makes it easier to use than any other timer-counter. And all this at a very attractive price!
