Multiplex®

Force-A

Thanks to more than 15 years of research,Multiplex® is a hand-held multi-parameter optical remote sensor for the fast, easy, and nondestructive measurement of constitutive and induced polyphenolics, as well as chlorophyll in plants. Multiplex® uses fluorescence technology with multiple excitations to measure various compounds in berry skins, leaves, fruits and vegetable skins.

MULTIPLEX® MEASUREMENTS 


Anthocyanin content, epidermal Visible absorbance by FER method
Flavonol content, epidermal UV absorbance by FER method
Chlorophyll content, Chlorophyll fluorescence emission ratio
UV-excited Blue-Green fluorescence (BGF)

The advantages of the technology are:


Simultaneousmeasurement of various
compounds
Remote and fastmeasurements (less than a
second)
Active sensing withmeasurements possible under
any ambient light conditions (day or night)
Non destructivemeasurements
No preparation of the plant
Portable device for fieldmeasurements (including
an internalGPS)

POLYPHENOLIC MONITORING MADE EASY


A measurement with Multiplex® takes less than a second by just pressing a button. The settings are easily configured through a user friendly interface on the touchscreen. Data are stored on a SD card and are also displayed on the LCD screen. The data can then be handled with common data presentation softwares. The sensor includes an internal GPS for a georeferencing of the data and field mapping. In its field portable version, Multiplex® has a long life battery designed to keep measuring all a day long and it can then be recharged in three hours.

APPLICATIONS
When used in conjunction with other agronomical data, Multiplex® can also provide inputs for decision support systems concerning fertilisation requirements, crop quality forecast, weed infestation and presence of fungal pathogens.
