SA series – Grapes Analyzer
Bx / ph / T.A. / color / sanity of the incoming grapes
DESCRIPTION
The SA is a sophisticated analyzer able to measure different parameters of a sample of grape must at the time of delivery to the wine processing plant. The standard configuration of the unit is Bx only but, as an option, it is possible to add pH, Total Acidity, color and grapes sanity measurements. The design of the system is modular: you may start with one parameter and add the other ones at your convenience. The analysis cycle (sampling, measuring and washing) is fully automatic and after measurement, the SA displays the results in the selected scale: it can be connected to an external printer and/or to the processing plant’s management system. The sample to be measured may be delivered to the SA both manually and automatically: in the automatic configuration, the analyzer is connected to the Maselli CC05 truck sampling probe by means of the must transfer unit. Even in the full configuration, all the cycle may be handled by only one operator using the joystick control panel. The farmers may see the results of the analysis in a dedicated remote display.
