Description
Overview
GAOTek Monitor Radiation is Mainly used to measure the wavelength of 0.3 to 3.2 micron solar total radiation. The meter is composed of double layer quartz glass cover, induction element, light screen, desiccant and other parts. The induction element, which is the core of the table, consists of a fast responding wire-wound electroplating thermopile. When the temperature rises when there is sunlight, it forms a thermal electromotive force with the cold contact on the other side, which is proportional to the solar radiation intensity. The double glazing is designed to reduce the effect of air convection on the radiation table.The inner cover is designed to block the infrared radiation of the outer cover itself.
