AGROSTA®ROXANNE : Used as

colorimeter for fruits

Even if our Roxanne is a versatile colorimeter, it

is particularly suitable for fruits and vegetables

Dedicated to food, fruits and vegetables,

research, pharmacy, chemistry, our Agrosta

Roxanne is a colorimeter that measures along

the visible range and infrared. You can use it to

classify very accurately your samples (For

example classify fruits by maturity, or milk fat

content..)

Agrosta Roxanne can detect differences that the

human eye cannot see, and thus the

classification of your samples is extremely fine

The new version measures the L*a*b and RGB

(between 0 and 255) as well as the spectrum

values for 9 wavelengths including IR Have a

look on the video hereafter on how Agrosta

Roxanne has first learned the CTIFL color chart

for strawberry, and has measured a batch of

strawberry according to this chart afterwards

Recording a paper color chart works well with

quite opaque fruits (Like strawberries, avocados

or cherries), but is not recommended on semi-

transparent fruits like tomatoes. For tomatoes,

Roxanne has to learn the maturity levels on real

tomatoes

The data can be exported to Excel. The color of

each sample is displayed on the screen (bottom

of the window)

Roxanne is a good solution for measuring color of

Cherries, blueberries, raspberries, blackberries,

strawberries, apricots, apples, pears, onions,

bananas and many more..

Its accuracy is extreme, and it is provided with a

calibration miror

2022 Improvements : Roxanne provides now data

using RGB and CIELAB referentials as well - It is a

very complete PC driven colorimeter
