The Renewable Energy Monitor is a battery operated monitoring and evaluation device with measurement software the provides a 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 - so that you can make direct solar and wind energy measurements. Horizon developed the Renewable Energy Monitor to allow you to avoid using the multimeters confusing setup and cumbersome computations in order to provide an immediate, graphical way for recording data directly- with no formulas and nothing to calculate. Numerous experiments and evaluation activities for hydrogen fuel cells, miniature wind turbine kits, and solar panels will now be quantifiable in real time for voltage, current, power, joules, resistance, and even RPM speed. Compatible with any of Horizon's clean energy educational kits!
