Higher accuracy, wider bandwidth, more features
WT3000 integrates high-precision measurement with a variety of special functions, and is a truly innovative measurement solution. *
The 8.4-inch large LCD display and LED range indicator have excellent visibility and operability.
Power measurement is more efficient
In the process of developing the WT3000, Yokogawa is committed to improving the effects of two aspects. On the one hand, while obtaining high measurement accuracy, it can also measure the power conversion efficiency of the equipment. On the other hand, it makes the synchronous power evaluation more convenient and faster, thereby improving the efficiency of equipment evaluation.
Innovative technology is used to enhance measurement stability;
WT2000 is favored by users for its high accuracy and excellent stability, and is regarded as a model of reliability. WT3000 relies on the measurement technology adopted by WT2000 and other WT series products. Improve the basic performance, make it have stronger functions and higher reliability. WT3000 supports new power control technology to provide you with more satisfactory measurement solutions in power and efficiency measurement.
A variety of external interfaces to choose from
WT3000 is the first model in the WT series with a standard PC card slot (ATA flash memory card slot). This interface can store data quickly and shorten the data processing time. WT3000 also comes standard with GP-IB interface. In addition, RS-232 serial port, Ethernet interface, USB peripheral port and USB communication interface are options. The diversity of interfaces allows users to select suitable interfaces for various devices, media and network environments.
