efergy e2 classic Energy Monitor with elink software

The e2 classic 2.0 is our latest and renewed version of our USB wireless energy monitor. It includes the elink 2.1, an innovative software package that allows you to track your energy usage on your computer. The e2 classic 2.0 helps you reduce energy and save money on your electricity bill by monitoring your home's/business' energy consumption.

The efergy e2 classic 2.0 electricity monitor is simple to install and use. The sensor wirelessly sends information about the amount of electricity you are using to the display monitor. The monitor converts this into kilowatt-hours, the standard unit which the electricity company uses to charge you. This shows how much you are using in the same units that are on your bill.

Input the amount your energy company charges you for each kilowatt-hour and you can see how much you are spending in electricity instantly. Make instant changes to save money, energy and the environment.
