NOTES ON SPECIFICATIONS
(1) All Skye sensors will work at levels of irradiance well above that found in terrestrial sunlight conditions,
room or growth chamber lighting. These are default working ranges, check individual calibration certificate.
(2) 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.
(3) 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.
