The MS-700N is designed to provide accurate and reliable solar spectral data in a rugged, weather-proof package for permanent outdoor installation.

The detector core is calibrated to NIST standards and temperature-controlled to give accurate solar irradiance measurement data within the UV-Visible-NIR spectral range from 350nm to 1050nm.

Analytik delivers solar radiation spectroradiometers to the UK and Ireland from EKO Instruments.

The MS-700N outdoor solar spectrometer is a unique all-weather spectral sensor with no moving parts to wear out. The detector core is temperature-controlled to provide long-term stability and accurate irradiance measurement data in the 350nm to 1050nm spectral range (UV/Visible/NIR).

Solar spectral irradiance varies as a function of air-mass and composition of the atmosphere, so measuring spectral irradiance is essential to understand the effects of non-uniform spectral energy distribution of the sun. While thermopile pyrheliometers and pyranometers are most suitable to quantify the total DNI or global radiation (W/m2), spectroradiometers give extra detail about the spectral energy distribution (W/m2/nm).

MS-700N is accurately calibrated with traceability to NIST international standards and issued with a calibration uncertainty budget. The rugged design of the optical diffuser and input optics make the MS-700N superior to any fiber optic input spectroradiometer, which are susceptible to mechanical vibration and handling. Eko solar spectroradiometers are designed for permanent installation, but are also suited as a portable reference spectrometer.

MS-700N has a separate power supply unit and is controlled through RS232/422 by a PC or data logger. Included PC software provides functions for operation, data management and data visualization. The open command protocol for defined system control functions allows end users to develop their own software for integration and control.
