  1. Littlemarky

    When they go they are gone

    I liked this product when new, but after a while they got to be more expensive to calibrate than buying a new one

    ✘ No, I do not recommend this product

  2. Jerryrz

    Simple and easy to use

    I have three of these for my business and they are an exceptional tool. These PQ meters provide all the necessary information to provide a customer with an excellent PQ study. In my business it helps me make the proper decisions to correct their inefficiencies.

    ✔ Yes, I recommend this product.

  3. REdge

    Easy to use

    I like how easy it is to set up. The only drawback is the limited amount of memory.

    ✔ Yes, I recommend this product.

  4. DairyD

    Must have for any Electrical Tech

    Have used on several jobs where coils where we had a more than usual amount of solenoids burning up or other odd electrical issues. We have found lots of issues that you couldn’t have tracked with just a multimeter. Wish it had more on board memory but the computer software works great with this logger.

    ✔ Yes, I recommend this product.
