Rubidium Counters

The PM 6685 and PM 6681 are available as R versions with a Rubidium Timebase.

Fluke Rubidium Counters are equipped with a Rubidium reference oscillator. The short warm-up time make them ready for use quickly after field transport or a change of location inside a building. The atomic resonance principle of rubidium standard is intrinsically 100 times more stable than the electromechanical crystal resonator. The built-in rubidium reference solves the practical problems of ensuring very high stability under tough field conditions.
