Horizon FCJJ Educational Renewable Energy Kits - Horizon FCJJ-24, The Renewable Energy Monitor is an educational evaluation monitoring device with measurement software which allows graphical display of performance characteristics on your PC. The REM can also display readings on the built-in LCD screen meaning it can be used with or without a computer, indoors or outdoors. The data gathered using the REM can then be used to optimise your renewable energy experiments and maximise the performance. Numerous experiments and evaluation activities using 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 the Horizon range of clean energy educational kits. Horizon FCJJ-24 Renewable Energy Monitor
