PMA 2145 Class I Pyranometer

PMA2145 is an ISO certified Class 1 pyranometer. The pyranometer is based on thermopile technology, which ensures wide spectral sensitivity as well as long-term stability and spectral flatness. The PMA2145 consists of 64 thermocouple junction sensing elements. The sensing elements are coated with highly stable carbon based on non-organic coating technology, which ensures excellent spectral absorption and long-term stability. The outer layer of the sensing element is two concentric Schott K5 hemispheres.
