Yokogawa 2038 Series Portable
Needle-Indicator Frequency Meters

A Broad Range of frequencies (45~500Hz) can be Measured with the broad selection of models.
True equivalent scale enables measurement of continuous frequency changes.
A wide range of voltages (50~300V) can be used.
RMS Response (differential system) minimizes waveform effects.
Anti-shock structure provided by taut-band design.

The Yokogawa 2038 Portable Needle-indicator Frequency Meter uses a transducer to convert a measured frequency to a proportionate DC current state, then shows the current as a DC current reading. The Transducer, combined with a high sensitivity moving coil type inducer based on Yokogawa's proprietary taut-band suspension system, provides a level of performance not possible with conventional frequency meters. In additional to frequency measurements for research labs and schools, the 2038 can be used as a standard for measurement control labs and field tests.
