Yokogawa 203831 Portable Needle-Indicator Frequency Meter, 45 ~ 65 Hz
The Yokogawa 203831 Portable Needle-Indicator Frequency Meter, 45 ~ 65 Hz uses a transducer to convert a measured frequency to a proportionate DC current, then shows the current as a DC current reading. The transducer, combined with a high sensitivity moving coil type indicator based on Yokogawa’s proprietary taut-band suspension system, provides a level of performance not possible with conventional frequency meters. In addition to frequency measurements for research labs and schools, the 203831 can be used as a standard for measurement control labs and field tests.
