The Amprobe ACD-41PQ clamp-on power quality meter provides a simple and effective way to verify if the electrical system is affected by harmonics. The ACD-41PQ is a True RMS clamp-on meter with enhanced troubleshooting capabilities as well as power analysis functions. For enhanced meter functionality an optional PC interface kit is available for data analysis.

Amprobe ACD-41PQ clamp-on power quality meters feature: an audible, continuity alarm; auto power-off; automatic polarity detection; low battery indication; peak hold; data hold and voltage overload protection for all functions up to 600 V AC/DC.

The Amprobe ACD-41PQ clamp-on power quality meter accurately measures AC/DC voltage, AC current, frequency, and temperature. Additionally, the meter measures total harmonic distortion to th 51st harmonic with accuracy from ±(1.5% rdg + 6d) to ±(4.5% rdg + 6d) depending on range. The The Amprobe ACD-41PQ also measures Active (W), Reactive (VAR) and Apparent (VA) Power with dual-display Power Factor readout.
