The environmental field requires robust, high-sensitivity analysis capable of complying with regulations in order to always meet the stringent target values that have been established to assure the safety of the water supply and protect the environment. Moreover, in laboratories where more than 100 samples are processed per day, increasing the throughput and saving energy are issues of concern.

Diffuse irradiance measurements: Diffuse Horizontal Irradiance measurements are performed with a thermopile sensor called Pyranometer mounted on a Sun tracker or shading ring. When the pyranometer is installed on an automatic sun tracker, the diffuse radiation can be measured in two different ways. Measuring Diffuse irradiance requires an accurate pyranometer with low offset properties. Duirng clear sky conditions the DHI irradiance (W/m2) is less than 20% of the total irradiance. Zero offsets lead to...
Solar Direct Normal Irradiance (DNI) represents the direct solar component and contains about 80% of the total solar energy budget on earth. Outside the atmosphere (AM0) the solar irradiance is considdered as a constant (1367 W/m2) that slightly fluctuates with a 11 year cycle. The DNI at the earth surface is highly variable due to the atmospheric conditions (clouds, aerosols, water vapor and molecules).
Spectral irradiance is the irradiance of a surface per unit frequency or wavelength. spectral irradiance of a wavelength spectrum is measured per watts per square metre per nanometre (W·m−2·nm−1). Spectroradiometers are devices designed to measure the spectral power distribution of a source. From the spectral power distribution, the radiometric, photometric, and colorimetric quantities of light can be determined in order to measure, characterize, and...Premium
Concentrating Photovoltaics (CPV) is driven by only direct solar radiation. To quantify the energy efficiency of a CPV system the total DNI and direct spectral solar irradiance, called spectral DNI, can be measured. Solar sensors are crucial during the phase of development and operation. Even at high sunny places, the composition and variability of the atmosphere strongly affects the solar spectral distribution and will impact on the energy yield and the decision on which cell type to use. The...

The construction building wall makes the most significant contribution to the reduction of building energy consumption. The total thermal losses of building constructions strongly depends on the environmental conditions (Location) and building construction (Material). On site measurements are possible with EKO thin film heat flow sensors which can be integrated with building walls. Evaluation of heat flow and thermal losses is inevitable during building design and engineering of energy-efficient floor heating...Premium
Conducting reliable and accurate solar radiation measurements requires some knowledge and attention: think of environmental influences (wind, rain/snow, soling), re-calibration (bi-annually), not to mention data processing, spectral effects, etc. Essentially, accurate broadband solar radiation measurements are obtained using two components: a suitable set of pyranometers, including an optional pyrheliometer (DNI sensor) with sun tracker, and an adequate data logger.Premium
