LR03 - Grapes Analyzer

The LR03 is a benchtop refractometer designed to determine the sugar content of grape must as loads arrive at the winery. Guided by a touch screen panel, the operator washes, rinses and measures the sample, while the vertical prism with automatic cleaning keeps suspended solids and emulsions from affecting the reading. Results can be displayed in multiple scales, printed, or transmitted via serial output to the plant's management system, giving quality staff a fast, repeatable check on incoming fruit.

Specifications

Application:

This equipment has been designed to measure the sugar content of grape must on delivery to the winery.

Measurement scales/limits:

0…30° % mass (Brix) alternative 0…18.3° % vol. conventionally calculated based on 16.83 g/l per 1 % in alcohol volume

Accuracy:

0.1° % mass or ±0.1% vol. ; the maximum tolerated error is applied to indications which are not rounded up

Notes:

The comparison in the various measurement scales refers to the nD/Bx ICUMSA conversion tables (1974)

Product temperature:

5… 40°C (41 … 104°F) with automatic compensation of the temperature measured by the internal PT1000 Temperature Probe in AISI 316 stainless steel

Quantity of sample analyzed:

~400 cc/measurement cycle

Positioning:

The instrument must be protected from direct sunlight
