SP-100

Wika Irradiance measurement Pyranometer Model SP-100 is an advanced, high-precision instrument designed for the measurement of global solar irradiance on a horizontal plane. It is engineered to meet the most stringent requirements for accuracy and reliability, making it ideal for use in meteorological networks, solar energy applications, and environmental monitoring. The pyranometer measures the solar radiation received from the entire hemisphere, integrating the direct, diffuse, and reflected solar energy. It complies with ISO 9060:2018 standards, spectrally flat Class A specifications. Model SP-100 has 180° hemispherical field of view ensuring comprehensive coverage of incident solar radiation.
