The Extech PM120 Appliance Power Monitor records power usage of home and work appliances for energy conservation and cost reduction analysis. Results can help determine if the electrical device should be replaced with a higher efficiency unit. The PM120 has a large dual LCD. The primary display shows Voltage, Current, Power, Power Factor and Frequency readings and the secondary display shows Total Time, Cost (cost of operation per minute, day, or week), Set, or Energy. The design includes a standard North American 3-prong electrical plug, front-socket connection, and backup battery that saves customized programs.
