Plug your grow lights, hydroponics systems or any other electrical unit into the Kill A Watt to find out how much energy they use! Find the culprit running up your electric bill and replace it with more energy efficient equipment. 

While connected to your electrical equipment, the Kill A Watt monitors and assesses power voltage (Volt), line frequency (Hz), and power factor (VA)with an accuracy of +/- 0.2 percent.

An easy-to-read large-text LCD display shows the kilowatt-hour consumption and can be calculated by the day, week, month, or even year. Kill A Watt can even detect voltage drops and brownout conditions.

One-year manufacturer’s warranty.
