Product Introduction

Ultraviolet radiometer is a precision instrument used to measure solar ultraviolet radiation (UVAB wavelength range) in the atmosphere. The instrument and data collector can provide information that the public cares about: UV index, UV erythema measurement, UV impact on the human body and UV special biological and chemical effects. Therefore, it has received much attention from meteorology, industry, construction and medicine, and is widely used in the research of erythema dose caused by sun exposure, comprehensive environmental and ecological effects, climate change, and ultraviolet monitoring and forecasting.

Product Principle

The ultraviolet radiation meter adopts ultraviolet light sensor, receives the electric signal of ultraviolet light wave, passes through a filter with a wavelength range of 280~400nm, and outputs RS485. The specially shaped diffuser can make the watch obtain a very good cosine response, and prevent the filter from direct sunlight, reducing drift and thermal modulation. A filter is installed on the top of the meter body to satisfy the spectrum transmission, reduce the influence of the external environment on the detector, and play a protective role. The watch has good sealing and weather resistance, allowing continuous outdoor work.
