SA series - Grapes Analyzer - Maselli Misure

The SA Series Grapes Analyzer delivers rapid, multi-parameter analysis of incoming grape must at harvest reception. In a single automated cycle, it simultaneously measures alcohol concentration (0–18% vol.), pH (2–14), total acidity (0–30 g/l tartaric acid), and color tonality with high precision and temperature compensation. Processing 500 cc samples in 70–90 seconds, the analyzer reduces manual testing bottlenecks and ensures consistent quality data for every batch, enabling faster winemaking decisions at the point of delivery.

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
