ZAB UV Radiometer is a precision instrument used to measure the solar ultraviolet radiation (UV AB wavelength range) in the atmosphere. The instrument can be used together with the data collector to provide information that the public cares about: UV index, UV erythema measurement, UV impact on human body and special biological and chemical effects of UV.
The ZAB UV radiometer uses a photoelectric detector to receive the electric signal of the ultraviolet light wave, and its output voltage is 0-200mV through a filter with a wavelength range of 280-400nm. The specially shaped scatterer can make the meter obtain very good cosine response, prevent the filter from direct sunlight, and reduce drift and thermal modulation.

Why double glass cover design？
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.
