Dualex
Who knows the health of your plants? Metos knows.
Dualex
The Dualex optical sensor gives you a simple and non-destructive way to quickly measure plant nitrate and chlorophyll.
RAPIDLY DIAGNOSE NITRATE AND CHLOROPHYLL IN YOUR PLANTS WITH A HAND-HELD LEAFCLIP
Catch the early signs of plant stress, due to nutrient deficiency and drought, before the onset of visible symptoms and subsequent yield loss. Thanks to a patented technology, this optical leafclip sensor is easy to use and gives you fast non-destructive measurements of the chlorophyll, flavonols and anthocyanins content in leaves.
ACCURATE MEASUREMENT OF CHLOROPHYLL
Chlorophyll plays a vital role in photosynthesis and plant development. Dualex measures the chlorophyll by analyzing the light transmitted through the leaf. Thanks to a chemical calibration made by FORCE-A, the chlorophyll is given in µg/cm² in the range of 5-80 µg/cm².
ACCURATE MEASUREMENT OF FLAVONOLS AND ANTHOCYANINS
Flavonols are mainly synthetized after light exposure. As a consequence, they are a good indicator of plant-light interaction history. Dualex measures flavonols and anthocyanins by analyzing the screening effect of flavonols and anthocyanins on chlorophyll fluorescence. Flavonols and anthocyanins content are given in relative absorbance units from 0 to 3 for flavonols and 0 to 1.5 for anthocyanins.
NBI®: NITROGEN BALANCED INDEX
Chlorophyll is often used as an indicator of plant nitrogen status. Several years of research and experimentation showed that polyphenols, specifically flavonols, are also good indicators of nitrogen status of plants. NBI® (Nitrogen Balance Index) combines chlorophyll and flavonols (related to nitrogen/carbon allocation). It’s a nitrogen plant status indicator directly correlated with massic nitrogen content. The NBI® is less sensitive to the variations of environmental conditions than the chlorophyll (leaf age, leaf thickness).
KEY BENEFITS
Dualex helps you keep an eye on the growth of your plants so you can maximize your yields:
- get an early look at the health of your plants before the eye can see visible signs of stress
- use information to proactively manage the nutrient needs of your crops before damage occurs
- instantly and accurately determine the measurement of chlorophyll, flavonols and anthocyanins in leaves
- the simple and non-destructive design is easy on your plants
