Special UV-Index Sensor EryF Features of the EryF special UV-Index Sensor The UVI Sensor EryF is based on our approved broad band UV-Sensor TW30SX and uses a Filter leading to excellent accordance with the erythema action curve of the human skin. The EryF is designed for use as a erythema sensor according to ISO 17166 CIE S 007/E (2000) – DIN 5050. It is optimally suited to feature high quality instruments for exact measurements of the UV Index. Overview on the advantages: • UVI precision is possible up to ± ½ UVI • the Sensor’s current is directly proportional to the UV-Index • also suited for sun tanning bank dosimetry • Based on approved TW30SX technology • Schottky-type photodiode • Intrinsic visible blindness due to wide-bandgap semiconductor material • large photoactive area • designed to operate in photovoltaic mode • hermetically sealed metal TO18 housing and UV-glass window • we are able to manufacture up to 2.000.000 pcs. per year.
