Description

LP PYRA 10 : Pyranometer (ISO 9060 Secondary Standard)  

The LP PYRA 10 is a Pyranometer classified as “Secondary Standard” in accordance with ISO 9060 and according to the publication "Guide to Meteorological Instruments and Methods of Observation”, fifth edition (1983) of WMO. The pyranometer LP PYRA 10 measures the irradiance on a flat surface (Watt/m2). The radiation measured is the sum of direct solar irradiance and diffuse irradiance (global radiation), Shadow ring (Optional) is equipped with an adjustable shadow ring for the measurement of diffuse radiation only.

Pyranometer (LP PYRA 10) 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.

The pyranometers LP PYRA 10 is based on a thermopile sensor which surface is covered by a matt black paint so to allow the instrument not to be selective at various wavelengths. The spectral range of the pyranometers is determined by the transmission of the two glass domes. The new sensor allows a response time less than the requirements of the ISO9060 standard for classification of Secondary Standard pyranometers (response time is generally less than 6 seconds, where ISO9060 standard requires a response time less than 15 seconds).

Recommended use:-

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