    Fantastic Tool

    I been in the automotive field 25+ years this tool is just the right size for checking current draws and how much amperage a motor or pump is pulling.

    ✔ Yes, I recommend this product.

    Quick & easy to use, a HUGE time-saver

    I used this amprobe at a local community college, and it was a huge time saver and handy tool to make instant readings on current and voltage in a small motor. We used it a great deal to learn about electric motors. I don’t even need one in the near future and bought one anyways just in case, since the price was great too. Can’t wait to find a reason to use it again. Great tool!

    ✔ Yes, I recommend this product.

    A great little meter for use in the Home

    The clampon feature is great for measuring AC currents.

    If you want to measure DC currents the inline wire method provides the way

    ✔ Yes, I recommend this product.

    Love this Amprobe!!!

    I have been doping service work for a long time and over the years have used many different brands of meters and ammeters.
    I got this mini version since I usually work on wiring that allows this unit to operate. I have had large units that are too big and buklky. This one is perfect for my application.

    ✔ Yes, I recommend this product.
