Pyranometers for accurate measurement of solar radiation - 1

Pyranometers For the Accurate Measurement of Solar Irradiance Installed around the world by national networks Specications to ISO 9060:1990 and IEC 60904 standards Widely used within World Meteorological Organisation scientic programmes The broadest range of pyranometers and accessories available Introduction Solar radiation drives almost every dynamic process on the Earth’s surface and above, from ocean current circulation to the weather, and life itself. Precise long-term measurements of the radiation budget at the surface are fundamental to understanding the Earth’s climate system. Rising fossil fuel costs and the need to reduce Carbon footprints has produced a rapid growth in the market for ‘green’ energy, in which the fastest growing sector is solar power. Scientists, researchers and commercial companies in requirements of ISO 9060:1990 and are fully traceable to renewable energy, climatology, weather, agriculture, water the World Radiometric Reference (WRR) in Davos, resources and environment all require accurate and reliable Switzerland, where Kipp & Zonen instruments form part of measurements of solar radiation. The measurement is made the World Standard Group. by pyranometers, which are radiometers designed for measuring the total (global) irradiance on a plane surface Our top level pyranometers have exceptional levelling resulting from radiant uxes in the wavelength range from accuracy, built-in temperature sensors and a test certicate with individually measured directional and temperature responses. These important features ensure the highest Kipp & Zonen has been manufacturing pyranometers for over accuracy measurements. Kipp & Zonen pyranometers are 85 years. We produce models at all price and performance designed for a long operating life with simple maintenance points, up to the very best available. All comply with the and a wide range of accessories is available.

Pyranometers for accurate measurement of solar radiation - 2

Kipp & Zonen pyranometers have been developed to be To achieve the required spectral and directional characteristics suitable for use in all environments, from the Antarctic to CMP Series pyranometers use thermopile detectors and glass deserts. They are installed around the world for meteorology, or quartz domes. All models have built-in bubble levels and hydrology, climate research, solar energy, environmental and adjustable levelling feet. The waterproof connectors have materials testing, greenhouse control, building automation gold-plated contacts and are tted with 10 m of high quality...

Pyranometers for accurate measurement of solar radiation - 3

CMP 21 is similar to CMP 11 but has individually optimised temperature compensation. A standard thermistor sensor is tted to monitor the housing temperature. Each instrument is supplied with its own temperature and directional (cosine) response data. It is the choice for scientic use and in top level solar radiation monitoring networks such as the Baseline Surface Radiation Network (BSRN) of the World Meteorological Organisation. CMP 22 has all the features of CMP 21 but uses very high CMP22 quality quartz domes for a wider spectral range, improved directional response, and reduced thermal...
