Scattered radiation sensor

Scattered radiation sensor is an instrument that measures the scattered radiation of the sun, measuring the scattered radiation or the sky radiation behind the direct shadow part.Scattered radiation sensor consists of two parts: the total radiation meter and the halo ring. The function of the halo ring is to ensure that it can continuously block the direct sun radiation from sunrise to sunset. The halo ring consists of a halo ring, a ruler, a screw adjusting spiral, a bracket, and a chassis. The width of the halo ring is 65mm and the diameter is 400mm. It is fixed on the screw adjustment spiral of the ruler, and the latitude scale and declination scale are engraved on the ruler. The ruler and bracket are fixed to the chassis and should be fixed according to the geographical latitude of the shooting location.
