Sefram9858 Solar Power Meter
The Sefram9858 solar power meter is an instrument for measuring the intensity of solar radiation (measurement of electromagnetic waves). It can also be used to determine the optimum angle of incidence when positioning a solar panel. The Sefram9858 solarimeter is also ideal for meteorology (sky brightness) or for measuring light received on the ground in forests or greenhouses.
- Solar power measurement.
- Detachable sensor for remote measurement.
- Min., max., and hold functions.
- Selectable measurement units: 1 W/m² or 1 BTU/(ft²*h).
- Adjustable auto shut-off.
- Tripod slot under sensor.
- Very easy to use.
