Hioki portable power meters and analyzers are best in class power measuring instruments for measuring single to three-phase lines with a high degree of precision and accuracy. The new and improved PQ3198 is a power quality analyzer for monitoring and recording power supply anomalies, allowing their causes to be quickly investigated, and also for assessing power supply problems such as voltage drops, flicker, harmonics, and other electrical issues. New features include the ability to drive current sensors straight from the PQA and enhanced recording capabilities.
