Model SPF-290AS Automated UV Transmittance / SPF Analyzer

• Solar Light's versatile SPF-290AS UV transmittance/sun protection factor analyzer is an integrated turnkey UV spectrometer, designed and optimized for the determination of SPF values on variety of sunscreens and cosmetics, as well as material testing. This attractive, standalone desktop device reduces the need and associated costs for in-vivo testing. Covering both UVB and UVA spectral regions, the system automatically scans from 290 to 400 nm, accumulating and storing data at distances of 1, 2 or 5 nm. The monochromatic protection factor (MPF) is determined for each selected wavelength and is used to calculate the SPF value, using the solar irradiance and the software-programmed erythema constant (but can be easily modified).
