SA series - Grapes Analyzer

The SA series analyzer automates sampling, measurement and washing to characterize incoming grape must right at the receiving dock, cutting waiting times to just minutes per truck. Starting from a standard Brix-only configuration, the modular design lets wineries add pH, total acidity, colour (PQ/Tonality) and sanity measurements as needs grow. Results can be sent to a printer, plant management system or a farmer-facing remote display, and the unit connects directly to Maselli's CC05 truck sampling probe for fully automatic operation with a single operator.

Specifications

Application:

Measure and analysis, in cycles with automatic loading, of a sample of grape must at the time of reception of grapes

Limits/measurement scale:

0…18% vol. calculated conventionally on the basis of 16.83 g/l per 1% in volume of alcohol

Accuracy:

±0.1% vol. maximum tolerated error is applied to indications which are not rounded off

Concentration measurement:

For instruments marketed in countries where type analysis is not envisaged

PQ/Tonality measurement
