ABSTRACT:
This invention relates to a device for measuring the ultraviolet radiation in the UV-A and/or UV-B range with detector means for said ranges, switching means for considering the skin sensitivity, electronic means for evaluating the signals derived from the detector, means for displaying the intensity and/or the dose of the radiation and second switching means for selecting one of different quartz lamps in said ranges. This device is in particular adapted for digitally measuring the dose of harmful erythem effective UV-B radiation or the dose of therapeutic healing UV-A radiation. This invention further relates to a method for producing and calibrating said devices, in particular the shunts contained in said second switching means which enables to select different quartz lamps with different line intensities.
