The Renewable Energy Monitor is an educational evaluation monitoring
device with measurement software for graphical display of performance
characteristics on your PC. It offers a 2 line LCD screen for viewing
measurements that you cycle through at the push of a button - avoiding
the multimeters confusing setup and cumbersome computations. The
Renewable Energy Monitor is battery operated so it can also be used with
or without a computer - indoors or outdoors - where you can make direct
solar and wind measurements.
