5 reviews for Amprobe DM-III Multitest 1000A Power Quality Recorder

  1. Amprobe

    We’re sorry to hear your tool did not meet your expectations. The DM-III is no longer being supported as we have released the new DM-5 Power Quality Analyzer as a replacement.

  2. DD4470

    Great device, mediocre software

    I’ve used Amprobe devices since the late 90’s – my first exposure being the DM-II. As always the devices are great; however, the software could use some updating. It looks pretty much the same as it did in 1997. It’s glitchy to install and the UI is dated. We often take readings for engineering firms looking to capture data. They don’t like that they need to install the full software suite to analyze the file and would like a small file viewing application.

    ✔ Yes, I recommend this product.

  3. recubal

    el producto me resulta my bueno, mi interes es conseguir un juego de pinzas amperimetricas de menor rango de corriente

    quisiera conseguir un juego de donas amperimetricas flexibles para mejorar la presicisión a bajas corrientes.

    ✔ Yes, I recommend this product.

  4. Wina

    Great product

    Identify voltage sags and swells,harmonics,high-frequency noise and interruptions.This product has accurate measurements and can effectively locate issues and identify solutions.

    ✔ Yes, I recommend this product.

  5. chacoo
