Current, Leakage & Power Quality Instruments

Precision Current Sensing and Power Quality Analysis for Electrical Maintenance

Current, leakage, and power quality measurement instruments cover everything from routine electrical maintenance clamp meters through to precision current sensors and power quality analyzers used in energy auditing and grid compliance work.

This range spans the full MEWOI7000-series AC/DC leakage current clamp family, current sensors using Hall effect, Rogowski coil, and fluxgate technologies, current transformers for metering and protection, and power quality analyzers and clamp meters measuring harmonics, flicker, THD, and energy consumption.
