Fabric UV resistance tester also known as SPF & UPF Tester, anti-UV performance tester , anti-UV transmittance tester. Reflective, transmission of these two modes is the basic means of spectral measurement. To achieve these two modes of spectral measurements, usually require spectrometers, light sources, optical fibers, measurement scaffolds, standard reference samples, and measurement software. For the different types of samples, in order to obtain the best spectral data, reflection, transmission of these two basic models will evolve into more forms. Ultraviolet transmittance tester uses CCD detector, do not scan, save time, especially when the sample is more obvious at the same time because there is no scan, there is no raster calibration, spectral distortion caused by the results of instability is not accurate The At the same time the use of LED light source, good stability, the intensity is adjustable, resulting in a small heat, s...
