Solar Mearsuing Device, 0 to 2000 W

Gauss Meter with integrated sensor that determines energy efficiency in photovoltaic systems / also used to find the optimum location for new installations. Measuring range: 0 to 2000 W/m2 or 0 ... 634 BTU/(ft2 x h) Resolution: 0.1 W/m2 or 0.1 BTU/(ft2 x h) Accuracy: ±10 W/m2 or ±3 BTU/(ft2 x h) or ±5%; whichever is greatest in sunlight. Minimum, maximum and data hold functions. Built-in datalogging capability allows for long-term recording of measurements over time. Powered by 4 x AAA Li-ion batteries for approx. 16 days of continuous use at full charge. RS-232 data port for downloading measurement data to PC. Includes CD-ROM with Windows-compatible software for detailed data analysis. deal for solar panel site surveying, installation, inspection and monitoring as well as for solar energy research and product development.
