Description

LP PYRA 03 : Pyranometer (ISO 9060 Second Class)

LP PYRA 03 Pyranometer measures the irradiance on a plane surface (Watt/m2). Measured irradiance (Global Irradiance) is the result of the sum of direct solar irradiance and of diffuse irradiance.

Delta Ohm manufactures Second Class LP PYRA 03 Pyranometers with calibration certificate, which fully comply with ISO 9060 standards, and meet the requirements defined by the World Meteorological Organization (WMO). A 10 meter long cable, These are strong and reliable ground-based instruments, especially designed to be used under all weather conditions. They are suitable for installation on the field. No power supply is needed; Pyranometers generate a voltage, Every pyranometer is calibrated separately and is supplied standard with a WRR (World Radiometric Reference) Report of Calibration.

LP PYRA 03 Pyranometer is based on a thermopile sensor. The thermopile sensitive surface is coated with a black matt paint, which allows the pyranometer not to be selective at different wave lengths. The pyranometer spectral range is determined by the transmission of the glass dome type K5.

Recommended use:-

• Atmospheric research
• Weather stations
• Climatology
• Energy saving research
• Productive efficiency test of Photovoltaic plants etc.
