Easy to use, cost-effective and accurate for diverse applications
Product Overview
The WT300E series is the enhanced version of Yokogawa's 5th generation of compact power meters. As the world's best-selling power meter, it is the instrument of choice for a wide range of applications in production testing, quality assurance, and research & development.
WT300E power meters are easy to use, cost-effective and accurate for diverse applications including testing of electric devices, development and evaluation of home appliances and induction cookers, battery and DC-driven device testing, and conformance tests on uninterruptable power supplies.
The exceptional low power performance of the WT300E and power consumption software enables users to easily test their instruments to Energy Star, SPEC and standby power standards.
