    Instruments and analyzers for accurate solar radiation measurements

    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.

    Instruments and analyzers for solar radiation measurements in PV applications

    Solar radiation is not only the driving force behind the Earth’s weather phenomena, it also drives photovoltaic energy production. One day of solar energy received by the Earth exceeds the amount of worldwide energy consumption per year. Exploring this merely inexhaustible source of energy - either by direct transformation of radiant energy into electricity or by indirect energy production via wind, waves, etc. - seems to be the obvious way to go. In this context solar radiation measurements are of...

  • Environmental radiation monitoring

    Every day, wherever we go, we are exposed to minute amounts of environmental radiation.* This environmental radiation is emitted continuously, day and night, from various objects and substances in the natural world and our living environment.

    Most environmental radiation consists of three types: alpha rays (α), beta rays (β) and gamma rays (γ).  HORIBA`s PA-1000 `Radi`...

    Instruments and analyzers for solar radiation energy budgets studies

    The Meteorological research community is very ambitious to understand climate changes and global impact on life. With modern advanced measurement equipment, e.g. satellites, remote sensing technologies and sophisticated computer models, multiple meteorological parameters can be analyzed at a large scale at the same time. As the climate system is very complex it is difficult to give accurate predictions of our future climate. We work with climate models, which are based on the consequences of impacts thus far...

    Infrared temperature measurement for calibration industries

    To ensure high-precision performance from temperature measurement devices, reliable calibration is required. This can be carried out on site or under laboratory conditions, using primary or reference standard sources. Primary calibration sources are traceable to National Standards via a certified probe installed in the radiation cavity. Reference sources achieve traceability either by comparison with certified thermometers, or through purchasing a calibration certificate.

    Instruments and analyzers for DHI measurements

    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...

    Determination of heavy metals in food

    This analytical procedure is intended for measuring the content of the elements (cadmium, lead, arsenic, tin, chromium and mercury) in the samples of food products by atomic absorption spectrometry with electrothermal atomization using an “MGA-915M” Graphite Furnace AA Spectrometer.

    The method is based on measuring resonance radiation absorption that occurs when the radiation passes through a layer of atomic vapor in the electrically heated graphite furnace of the “MGA-915M” AA...

    Instruments and analyzers for spectral irradiance portable solutions

    Reflection and transmission measurements on materials, vegetation, water or atmosphere give valuable information about biological, physical and chemical processes. Processes driven by solar radiation, in particular bands of the spectrum through the so called action spectra, can be analysed or quantified with a sensor senitive in the particular spectral band. The MS-720 portable spectroradiometer gives total freedom to be used in different applications and range of the spectrum between 350 - 1050 nm.

  • Distributed Temperature Sensing Technology for Stream Monitoring

    Temperature is an important factor in streams ecosystems. Heat tracers have been used to characterize contaminant transport, infiltration rates and energy exchange with groundwater, the atmosphere and radiation. The dynamics of these complicated water bodies is also affected by seasonal and diurnal patterns making characterization particularly challenging. Utilizing temperature measurements that capture spatial and temporal variations at stream ecosystem interfaces provides a mechanism for detailed characterizat...

  • Combined photo-radiometric probe for Museum & Metal Industry

    The combined photo-radiometric probe LP471P-A measures the two parameters of principal interest in the field of lighting, namely the ILLUMINATION (lux) and UVA IRRADIANCE (W/m2). The probe is composed by a luxmeter and an UVA radiometer. The signals of the two sensors are read and processed at the same time to visualize the relation between the two quantities expressed in µW/lumen. The two sensors are equipped with a diffuser for the correct measure according to the cosine law. The probe LP471P-A is particularly...
