UV Index Sensor - SKU 440

Product Specification

Skye have been designing and manufacturing quality, fully calibrated light sensors since 1983. As well as this UV Index sensor, the range also includes UVA and UVB sensors (see seperate datasheets).

This UVI Index sensor has a response closely matching the Erythema Action Spectrum, the damaging portion of the solar radiation spectrum associated with sunburn and skin cancer.

The UV Index sensor gives a voltage output which can be easily scaled to UVI values with an appropriate meter e.g. Apollo Display Meter (SKA 400) i.e. ranging from 0, low risk of sunburn to 11+, dangerous levels of UV).

The sensor is calibrated against a reference traceable to National Standards under full sunlight conditions, and so is ideal for long term datalogging on meteorological stations.

SKU 440 SPECIFICATIONS

(1) Main source of this error is uncertainty of calibration of Reference. Skye calibration standards are directly traceable to N.P.L. standard references.

(2) 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.

(3) Measured at 45º elevation over 360º.

(4) Maximum change in one year. Calibration check recommended at least every two years. Experience has shown that changes are typically much less than figures quoted.

(5) Times are generally less than the figure quoted, which is in milliseconds. They may be slightly increased if long leads are fitted, or those of a higher capacity cable.
