Product Specification
Skye Instruments Ltd have been designing and manufacturing quality, fully calibrated light sensors since 1983.
Skye offer sensors to measure light levels in the Ultraviolet A and Ultraviolet B wavebands. The wavelengths used in this UVA sensor are according to CIE standards.
The dimensions and overall look of these sensors are similar to that of our other sensors. The housing is black aluminum and sealed to IP67 standards.
The light sensor head is cosine corrected and has been designed with an integral amplifier to give a voltage output for use with most dataloggers, computers, PLCs, etc.
Sensors calibration is traceable to NPL and each sensor is issued with a calibration certificate.

(1) All standard Skye sensors will work at levels of irradiance well above that found in terrestrial sunlight conditions, room or growth chamber lighting
(2) Main source of this error is uncertainty of calibration of Reference Lamp. Skye calibration standards are directly traceable to N.P.L. Standard references.
(3) Cosine error to 80o is typically 5% max. Figures shown are for normal use sources, e.g., sun plus sky, diffuse sun, growth chambers, etc.
(4) Measured at 45o elevation over 360o
(5) Maximum change in one year. Calibration check recommended at least every two years. Experience has shown that changes are typically much less than figures
(6) Times are generally less than the figure quoted, which is in nanoseconds. They may be slightly increased if long leads are fitted, or those of a higher capacity cable
