This is a useful device for anyone who wants to measure illumination levels. It senses or detects brightness/lux of any environment. It uses long life silicon diode, spectral response filter and fully corrected for the angular incidence of light to ensure stability. Brightness or light intensity plays a very essential factor in determining the proper exposure for photograph as well as providing correct light intensity for each environment. It reads the intensity of light falling on the subject and measurements are taken from the subject position It has the approval of European Directives for essential health standards and safety requirements, you are assured that using this item is safe.
The data gathered are very useful information in maintaining the correct brightness of any environment applications like in the fields of cinematography, in scenic design, in determining optimum light level for a scene, in the general field of lighting, in reducing the amount of waste light used in the home, in ensuring proper light levels for plant growth. And even in measuring luminance in any environments such as illumination control, weather observation and work places like factories, offices, shops, schools, restaurants, beauty salons, electro-optical sources, research teaching, metallurgy building, industry inspection, agriculture research and many other environments.
