SOLAR TOTAL PYRANOMETER

The Middleton EQ08-S is a precision pyranometer for the measurement of global solar irradiance on a plane surface. It exceeds the international accepted specifications for a high quality pyranometer. The EQ08-S incorporates a second generation precision thermoelectric sensor that has exceptionally low directional error without compromise to signal strength or response time. The EQ08-SE version has an in-built amplifier to give a millivolt output for easy signal measurement.
