Watt's Up Pro Kill A Watt Monitor

Watts Up Pro is a simple to use plug-in kill-a-watt monitor to measure how much electricy any device is using. Simply plug any electrical device into Watt’s Up and the meter instantaneously displays the wattage being used, as well as 18 other values (see below), including average monthly cost. The device also records this data into non-volatile memory, so you won’t lose the date if power is lost. One thousand seven hundred data points are stored, starting with a sampling rate resolution of one second. It records any power interruptions, which is extremely handy when performing an audit of several devices. Watt’s Up is also capable of real-time logging. It even includes a payback calculator software utility, which automatically calculates the time required for a new energy efficient appliance to pay for itself.
