FAQ

What does mean FORCE-A?

FORCE-A means Fluorescence & Optoelectronics for the Research & Communication between Ecophysiology & Agriculture.

What is the technology used in FORCE-A sensors ?

The technology used to measure the chlorophyll with the le DUALEX® is transmittance, it is fluorescence for the MULTIPLEX®. The anthocyanins and the flavonols are mesured by absorbance for the 2 kinds of sensors. The phytoalexins are measured by the blue fluorescence for the MULTIPLEX 330™.

What are the units measured by FORCE-A sensors ?

For the buyers of our sensors (scientists), the data collected by FORCE-A sensors are relative indices and ratios. They do not have any unit. However, it is possible to convert the anthocyanin index in mg/l for red grape measurments thanks to the platform CUBA: http://max2.ese.u-psud.fr/cuba/

For our grapevine services (FA-VENDANGE™), the MULTIPLEX®  measures the anthocyanin values in mg/l. In the case of the service FA-VIGOR™, the grapevine nitrogen status is a ratio without unit (NBI).

For wheat service, the DUALEX® gives the harvest grain protein forecast in %, the measurements being performed at the flowering stage of the crop.

What is the DUALEX SCIENTIFIC™ ?

The DUALEX® is a leafclip used for the instant and non-destructive measurements of chlorophyll, polyphenols and the nitrogen status. We market 2 different models: the DUALEX SCIENTIFIC™ (indices of chlorophyll, flavonols and nitrogen status) and the DUALEX SCIENTIFIC+™ (indices of chlorophyll, flavonols, nitrogen status and anthocyanins).

What is the MULTIPLEX RESEARCH™ ?

The MULTIPLEX RESEARCH™ is a portable fluorometer used to detect the abotic stresses, including the nitrogen deficiency and the fruit maturity. The sensor gives the indices of chlorophyll, flavonols, nitrogen status and anthocyanins, in an instant and non-destructive way.
