  • What's Included
  • What does it really cost to run that electric water heater or energy-efficient refrigerator? Find out instantly by plugging it, or any other electrical appliance into Watts Up? PRO, this instantaneously displays the used wattage; as well as the cost, in actual dollars and cents! The Watts Up? PRO measures voltage and current information thousands of times a second, yet it is simple to use. Only six values are displayed in the main modes. Additional information is available in the detail mode. Clear English wording on the LCD is used to describe what is displayed.


    Super Fast Response Allows for Additional Data Collection
    Watts Up? PRO has an incredibly fast response time, enabling you to "see the surge" of power when appliances are first turned on. Input is via a 6 foot electric cord; output is via outlet on top of meter. The peak value display captures this surge so it is displayed even if it happens too fast to see live. The minimum voltage display shows the line quality and voltage dips. Minimum current and minimum watts are used to monitor variances in appliances that run continuously. Watts Up? PRO also measures true RMS power (including power factor) which is what utilities charge for.

    For Additional Analysis Tools, Choose Watts Up? PRO
    Watts Up? PRO offers all the features of the standard Watts Up?, but includes additional analysis tools, like the Payback Calculator, which automatically calculates the time required for a new energy-efficient appliance to pay for itself. Monthly savings are highlighted, and compared to the purchase price of the new appliance.

    The PRO version includes all the displays of Watts Up and records all the data into non-volatile memory, which can be retrieved even if power is lost. One thousand data points are stored, starting with a sampling rate resolution of one second. The sample rate resolution increases over time (sample rate equals total time divided by 1000) so years of usage can be accurately recorded. The included serial cable and software program allows the data to be quickly downloaded to a PC where the included software creates a data table and easily manipulated graphs. The data can also be exported in a comma-delimited format to popular spreadsheet programs for further analysis. Accuracy is of the displayed value, not the range. Some devices claim a smaller number for accuracy but it refers to the range. For instance, a specification of 0.2% of the range sounds good, but it is actually 3.6% of the display (.02 * 1800 = 3.6), which is a worse accuracy. For indoor use only.

    Looks like false advertising to me. What does it really cost to run that electric water heater Last time I checked, residential hot water heaters don't plug in. Maybe I'm missing something, but this certainly shouldn't be the sales pitch.

    We have used these meters professionally in hundreds of locations and unfortunately they are a very flawed product. In at least 10 percent of installations they yield erroneous readings showing 3,000w for a normal 15A circuit. In many other situations they lose the time of the measurements making the data unusable. The are probably fine for simple homeowner usage.

    Just started using the meter to determine idle wattage for TV and stereo. Haven't used the logging featuers yet, but there seem to be plenty of options. I did notice that one of the front panel buttons doesn't have much play and if you press the front of the case, the button actuates - seems there needs to be some extra space around the button. I may need to open the case to analyze the situation.

    It is too hard to understand. Not a simple as it reads in the catalog. I think I waisted my money.

    About the best I could find for the price. working mostly as I expected, I would like to have had a little more info at the meter instead of having to go to the PC interface.
