The WT300E series is an expanded version of the 5th generation of compact power meters. The world's best-selling power meter is the ideal tool for production line testing, quality assurance and research and development.
The WT300E series is easy to use, cost-effective, and accurate for a wide variety of applications, such as electrical appliance testing, development and evaluation of household appliances (e.g., induction stoves), battery and other DC appliance testing, and compliance testing of uninterruptible power supplies.
The WT300E series' ultra-low power and power consumption software allows users to easily measure devices against EnergyStar, SPEC, standby standards.
