2038 Portable Needle-Indicator Frequency Meter
Brand: Yokogawa Electric CorporationModel 2038 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.
Features- A wide Range of Frequencies (45 to 500 Hz) Can be Measured with the Broad Selection of Models
- True Equivalent Scale Enables Measurement of Continuous Frequency Changes
- A Wide Range of Voltages (50-300 V) Can be Used
- RMS Response (Differential System) Minimizes Waveform Effects
- Anti-shock Structure Provided by Taut-band Design
