MS-711 DNI Spectroradiometer:

The MS-711 DNI Spectroradiometer is a device that is used to measure the amount of solar radiation that is received on a surface. It is specifically designed to measure the direct normal irradiance (DNI), which is the amount of sunlight that is received directly from the sun and is not scattered or absorbed by the atmosphere.

The MS-711 DNI Spectroradiometer is equipped with a solar tracker that keeps the device pointed directly at the sun at all times, ensuring that the measurements are accurate. The device also features a spectroradiometer that measures the intensity of sunlight across a wide range of wavelengths. This allows for the measurement of not only the total amount of solar radiation received, but also the spectral distribution of the radiation.

The MS-711 DNI Spectroradiometer is a useful tool for a variety of applications, such as solar energy systems, meteorology, and atmospheric research. In the field of solar energy systems, the device is used to measure the amount of solar radiation that is received by solar panels, which is necessary for determining the efficiency of the system. In meteorology, the device is used to study the effect of atmospheric conditions on the amount of solar radiation that reaches the Earth’s surface. In atmospheric research, the device is used to study the effects of aerosols and other atmospheric constituents on solar radiation.

In summary, MS-711 DNI Spectroradiometer is a device that measures the solar radiation received by surface and specifically Direct Normal Irradiance(DNI). It equipped with a solar tracker which keep the device pointed to the sun always and Spectroradiometer that measures the intensity of sunlight across a wide range of wavelengths. It finds its applications in Solar Energy Systems, Meteorology and Atmospheric Research.

A unique all-weather sensor, the MS-711 DNI Spectroradiometer is designed to provide the most accurate direct solar spectral data outdoors and features a temperature-controlled detector, ensuring optimum performance in hot and cold conditions ranging from -10 to 50°C. The MS-711 DNI measures the spectral range from 300nm to 1100nm (UV-Visible-NIR) and includes NIST traceable calibration as well as a calibration uncertainty budget.

The MS-711 DNI has a compact, fixed collimating tube with a quartz window and window heater and can be attached to the STR-21G or STR-22G sun trackers using a robust aluminum mounting plate for automatic tracking.

The new generation grating and rugged optical design of the diffusor and input optics in the MS-711 DNI make it superior to any fiber-optic-based spectroradiometer by eliminating common issues with mechanical vibration and handling; it is ideal for permanent installation or as a traveling reference.

The MS-711 DNI has a separate power supply and can be controlled through RS232 or 422 on a PC or data logger. EKO also provides software options for device and data management and visualization. EKO Spectroradiometers deliver top-tier spectral measurements and detail about energy distribution (W/m2/nm), essential for effective PV or CPV cell research and performance analysis.
