Precision ground glass dome

Direct and Diffuse Radiation:

To accurately measure the direct and diffuse components of incident solar radiation, it uses a range of seven miniature thermopile sensors and a computer-generated shading pattern Besides, it can compute direct radiation by subtracting the diffuse from the global (total) radiation

Sunshine Duration:

The WMO threshold for bright sunshine is 120 W.m-2 in a plane perpendicular to the direct solar beam

The SPN1 uses an algorithm based on the ratio of direct to diffuse radiation It is combined with the absolute values to effectively estimate sunshine duration within a few percent of the WMO standard Requires neither adjustment or reposition to track the sun, which is a distinct advantage over devices with shadow rings No complex electro-mechanical assemblies and no burnt paper tracks to interpret

Outputs and Logging:

It provides 2 analogue voltage outputs for global and diffuse radiation A digital output for sunshine duration can be effectively connected to data loggers like Delta-T DL2e and Gp1 Accurate readings can also be obtained directly from the RS-232 port
