KÍNH PHÁT HIỆN SỚM NẤM BỆNH TURFSPY UNDERHILL
Disease, drought and weed invasion are plant and turf killers. But
by the time you see them it can be too late. TurfSpy™ glasses, with
stress detection technology developed by NASA, lets you “see into the
future” to identify problems 2-10 days before they are visible to your naked
eye. Keep your turf and vegetation healthy BEFORE serious problems arise.
• Shatterproof/polycarbonate stress detection lens
(ANSI approved safety lens)
• Wrap-around lens limits ambient light for optimal detection
• Sports frame with adjustable ear piece
• Lightweight case included
HOW IT WORKS
Dying vegetation absorbs and reflects sunlight differently then when
its healthy. The earliest signals occur at the outer limits of the human
visual spectrum, and are rendered invisible compared to the predominant
middle wavelengths. TurfSpy™ filters the light in the center so that fringe
spectra, which show early plant stress, become visible.
