The SPR5000 photobiological safety testing system can be used to measure parameters such as spectral distribution, spectral radiance, spectral irradiance, and effective ultraviolet radiation ratio (mW/m²), and evaluate the risk level of light radiation for ultraviolet sterilization and disinfection products, as well as various light sources, modules, lamps, pulse/flicker lamps, and electrical appliances. This evaluation is based on standards such as those for light radiation safety and household appliance safety requirements.
