The IF-02 analysis system consists of the RP-60 refractometer unit, which is the system’s analysis element, and the FM-01 receiver. The RP-60 refractometer unit is a portable, battery-powered device which allows the user to measure the refractive index of a must sample taken from a fermentation tank. The RP-60 combines a control unit with a touch screen display with an extremely compact, high-precision refractometric sensor. The portable RP-60 unit may be used both by means of a dedicated basin protected by the light or introducing it directly in the liquid. The data measured at the fermenters is downloaded via USB to the second element of the system; the FM-01 receiver which, usually placed in the laboratory, performs both data collection and processing functions. The software in the FM-01 processes the downloaded data and starting from the initial fermentation values (alcohol, nD, conductivity) calculates the variations in the alcohol and sugar content. It then produces graphs to show the alcohol increase curve in relation to the decrease in sugar.
|Application:||The IF02 Fermentation Measurement Assembly is a kit made up of a portable appliance and software to be installed on a PC. It can be used to measure natural must and fermented must/wines with control of the fermentation process in oenological plants.
|In-field measurement phases:||Once in the field it is necessary to:
Select the Tank/Batch on the touch screen using the scroll through menu.
Take a product sample and measure the conductivity (mandatory for the first analysis and optional for the following ones).
Dip the instrument into the must using the bowl provided or dip the probe directly into the container used to pick up the product sample.
Press OK to acquire the datum.
|Notes:||The mobile RP60 device always holds in its memory the last measurement performed, should the regular analysis return a result exceeding the previous one, the device notifies the operator of the anomaly.
Repeat the measurement phase for all the tanks in question, once all the measurements have been completed, repeat the synchronization phase using the FM01 on which it is possible to see the fermentation trend as a graph together with the list of measurements performed, etc..
