This Kill-A-Watt is used to help you cut down on
costs and find out what appliances are actually worth keeping plugged
in. The monitor will gauge how efficient your appliances really are. It is made with a large LCD display that will count consumption by the Kilowatt-hour, same as your local utility. You can calculate your electrical expenses by the day, week, month, even an entire year. Also check the quality of your power by monitoring Voltage, Line Frequency, and Power Factor. Now you'll know if it is time for a new pump or if your current one is still saving you money.
