PMA2145 is an ISO certified first level pyranometer.The pyranometer is based on thermoelectric stack technology, ensuring wide spectral sensitivity, long-term stability, and spectral flatness. PMA2145 consists of 64 thermocouple junction sensing elements. The sensing element is coated with highly stable carbon based on non organic coating technology, ensuring excellent spectral absorption and long-term stability. The outer layer of the sensing element consists of two concentric Schott K5 hemispheres.
