Razon+ is a smart sensor that accurately measures both direct normal irradiance (DNI) and diffuse horizontal irradiance (DHI) from the sun and sky, enabling it to provide very reliable values of global horizontal solar irradiance (GHI) and sunshine duration. The sensor is fully compatible with the Orbit 360 data logger.
RaZON+ includes two Smart irradiance sensors; a pyrheliometer (PH1) to measure DNI and a shaded pyranometer (PR1) to measure DHI. The innovative features of the pyrheliometer minimize the effects of soiling when operated unattended in remote locations, without compromising the high accuracy of the instrument. Both the pyrheliometer and pyranometer are based on quartz diffuser technology.
RaZON+ measures DNI and DHI and calculates GHI, as this minimizes uncertainty in the pyranometer readings and provides a more accurate and reliable measurement than using an unshaded pyranometer to measure GHI.
