Yokogawa offers a wide range of portable Analog and Volt meters for making measurements on the go. We also offer frequency, Watt, Power Factor, and even miniature portables for varies applications.
This panel-mounted power meter and energy meter with a large, three-row LED display integrates all the measuring functions required for power management in locations such as factories and buildings into a single unit.
With the objective of working toward the preservation of the global environment by saving energy and performing equipment maintenance, the PR300 is designed to display and output the energy of various types of electrical equipment.
Models 2011 and 2012 ammeters & voltmeters are moving coil type instruments using a taut-band suspension system. The suspension system provides excellent reproducibility without friction, and strong resistance to shock impact. These precision instruments combine a magnetic circuit (sandwich mechanism) that blocks the effects of external magnetic fields, and a superior temperature compensation circuit.
Models 2013 and 2014 ammeters & voltmeters are moving iron type instruments using a taut-band suspension system. The suspension system provides excellent reproducibility without friction, and good resistance to shock impact. A cap shield mechanism serving to reduce external magnetic fields, a superior temperature compensation circuit, and other components ensure stable performance.
Model 2016 consists of thermocouple type ammeters and voltmeters with four different measurement ranges. They are designed to provide true RMS values of inputs, so they can be used to measure high-frequency currents and voltages (DC) up to several MHz (the maximum frequency for the voltmeter is 100 kHz). The indicator is based on a taut-band suspension system, which eliminates friction, provides good resistance to vibrations and shock impact, and ensures excellent characteristics.
Model 2017 voltmeter is a rectifier type, Class 0.5 voltmeter designed for the audio frequency range.
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.
Model 2039 is a revolutionary series of portable wattmeters in which a power factor is used to operate the DC indicator. This is done using a transducer which provides a DC current proportionate to the voltage-current phase by means of a circuit. Model 2039 can be used in single-phase and balanced three-phase circuits. The electronic 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 power factor meters.
Model 2041 single-phase wattmeters and single-phase low-power-factor wattmeters and Model 2042 three-phase wattmeters are electrodynamometer type wattmeters with indicators based on taut-band suspension. They can handle DC and frequencies from 25 Hz to 1000 Hz, and provide excellent power factor characteristics. These instruments are shielded with dual permalloy sheets as protection against external magnetic fields.
The E series of miniature portable ammeters & voltmeters consist of JIS C 1102-2 Class 1.0 and Class 1.5 instruments. The taut-band suspension system is used in the moving parts of models 2051 and 2052 to eliminate friction and provide strong resistance to shock impact.
