The CEL-NP2000-Sun180 solar optical power meter is mainly used for outdoor measurement of total solar radiation with a wavelength range of 300nm~3000nm. It can test the optical power radiation value of solar radiation at a continuous all-weather angle of 0-180 ° and achieve all-weather measurement. The solar optical power meter can measure the reflected radiation value when the sensing face is downward, and can also be used to measure the solar radiation incident on the inclined plane. The scattered radiation can be measured by adding a shielding ring.
Solar Optical Power Meter can be widely used in outdoor meteorology, solar energy utilization, solar measurement, agriculture and forestry, building materials aging, atmospheric environment monitoring and other departments to measure solar radiation energy.
The solar optical power meter is composed of double quartz glass cover, sensing element, light shield, meter, desiccant, etc. The double glass cover is used to reduce the influence of air convection on the radiometer. The inner cover is designed to cut off the infrared radiation of the outer cover itself. The sensing element is the core part of the solar optical power meter, which is composed of a fast response wound electroplating thermopile. The sensing surface is coated with special matt black paint and hot nodes. When the sunlight illuminate, the temperature rises, and the temperature difference electromotive force is formed with the cold nodes on the other side. The electromotive force is proportional to the solar radiation intensity to achieve real-time measurement.
