The Amprobe ACD-45PQ is a compact digital clamp meter capable of measuring power, energy and power factor on a single and three-phase systems (balanced and unbalanced). Ultra-slim jaw design allows the user to clamp around conductors in confined and difficult to reach places. This digital clamp meter is also true-rms sensing takes reliable AC/DC voltages measurements up to 600 V.

  1. energreen

    cheap and great features with accuracy

    currently I´m using this product which I could compare with my power quality analyzer which is calibrated and it shows the same values I´m very happy with this product….

    ✔ Yes, I recommend this product.
