The UVI Sensor ERYCA is a further development of our
product EryF. With an additional filter the accordance with the erythema action
curve of the human skin has been further improved. The ERYCA is designed for
use as an erythema sensor according to ISO 17166 CIE S 007/E (2000) - DIN 5050.
It is optimally suited to feature in high quality instruments for exact
measurements of the UV Index.
