Middleton Solar - Model ER08-S and ER08-SE -Solar Total Pyranometers

Very fast response time is ideal for solar Photovoltaic Power Plant monitoring. The ER08-S Pyranometer features an innovative new design of detector with very low zero off-set and fast thermopile response to give reduced measurement uncertainty in comparison to conventional pyranometer designs that use an exposed blackened thermopile. The detector incorporates a cosine-corrected entrance aperture, a compact integrating cavity, and an encapsulated thermopile with a Field-Of-View restricted to the cavity. The Middleton Solar ER08-S exceeds the ISO 9060:1990 specifications for a very high quality Secondary Standard Pyranometer. The ER08-SE version has an in-built amplifier with a millivolt output for easy signal measurement.
