4 reviews for Amprobe DM-III Multitest F 3000A Power Quality Recorder

  1. Scott13

    Worth the investment

    This meter has a lot of useful features that can be used to monitor services, equipment, generators or individual circuits and grounding test capabilities. It can be used to record before and after any work done to document savings on power factor correction, energy efficient lighting, VFD’s instead of cross the starters. Used in Harmonic recordings. Drawbacks are the limitations on single phase and delta recordings and the limited battery life. Otherwise it is worth the money.

    ✔ Yes, I recommend this product.

    Great Tool to have.

    Replaced an older version DM II wiith this recorder.
    Much better reading quality and downloading is a breeze.
    Has more user friendly features and is 1/2 the size of the old unit. Has ground testing capabilities which the older unit did not have
    Definitely worth the investment !!!!!!!!!!!!!!!!!!

    ✔ Yes, I recommend this product.
