Portable Needle-Indicator Frequency Meters 2038 (DISCONTINUED)
Notice: This product was discontinued on Dec 27, 2019.
See this replacement product:
Model 2038 frequency meter 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 2038 can be used as a standard for measurement control labs and field tests.
