ERYF

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 w e are able to manufacture up to 2.000.000 pcs. per year.
