solar irradiance inspection device
Kipp & Zonen
RaZON+ is an all-in-one system 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 integrated data logger presents the irradiance measurements in W/m2, sunshine duration in hours and energy in kilowatt hours/m2. With the Wi-Fi connection you can easily set-up and configure RaZON+ using any smart device, such as a tablet.
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 minimise 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 minimises uncertainty in the pyranometer readings and provides a more accurate and reliable measurement than using an unshaded pyranometer to measure GHI.
