Introduction
An Oechsle Brix refractometer is a hand-held optical instrument used to measure the sugar content of the grape musts and the juices, and it is used in the viticulture, the winemaking, the fruit processing, and the food industries. The refractometer measures the refractive index of the sample, which is related to the concentration of the dissolved solids, primarily the sugars, and it provides the readings in the Oechsle degree, which is used for the assessment of the grape ripeness and the potential alcohol, and in the Brix degree, which is used for the measurement of the sugar content, and it is calibrated for the grape and the fruit measurements; the Oechsle Brix refractometer consists of the optics with the prism and the dual scales, the sample well, and the eyepiece, and it is used by the placement of a few drops of the sample on the prism and the observation of the scale, with features such as the automatic temperature compensation; the Oechsle Brix refractometer is used for the measurement of the sugar content of the grapes and the musts, for the assessment of the ripeness, for the prediction of the alcohol, for the monitoring of the fermentation, for the quality control, and for many other applications; the Oechsle Brix refractometer is an essential instrument for the winemaking. Oechsle Brix refractometers are used in the vineyards, in the wineries, in the laboratories, in the fruit processing, and for many other applications. With their Oechsle and the Brix scales, Oechsle Brix refractometers are essential for the grape and the wine analysis.

FAQ
Q1: What testing scenarios is this instrument mainly applied to?
A: The Oechsle Brix refractometer is used by winemakers and vineyard technicians to measure grape must sugar content in Oechsle degrees and Brix percentage. It supports harvest timing decisions, fermentation start-point assessment and juice quality monitoring in small and medium wineries where benchtop density meters are not practical for field use.
Q2: What standards does the instrument comply with?
A: The measurement follows refractometric methods referenced in OIV recommendations and GB/T 15038 general analytical methods for wine. Oechsle scale conversion is specific to must density and should be used with the appropriate regional conversion table.
Q3: What is the warranty period for the whole machine and key components?
A: The refractometer carries a 12-month warranty against manufacturing defects. The optical prism and scale mechanism are covered, while the calibration tool and case are accessories. Damage from dropping, scratching the prism or corrosive exposure is excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation is simple: apply a sample drop, close the cover and read the scale. No professional training is required, but users should calibrate with distilled water before use and clean the prism after each sample to prevent residue buildup.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Zero check with distilled water is recommended before each use session. Accuracy verification against a reference sucrose solution every 6-12 months is sufficient for most field applications.
Q7: Are supporting consumables universal? What about the long-term procurement cost?
A: There are no recurring consumables. The pipette and cleaning cloth are standard accessories with negligible replacement cost. Long-term ownership cost is minimal.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes scale combination, range and branded packaging for winery supply programs. Minimum order quantities apply for custom versions.
Q9: Does the purchase include on-site installation and commissioning service?
A: No installation is required. The package includes calibration tool, pipette, cloth and case. On-site training is not included for handheld units.
Q10: What types of samples are compatible with this equipment?
A: Designed for grape must, wine and clear fruit juices. Opaque or particle-heavy samples should be filtered first. Strong acids, alkalis or abrasive particles can damage the prism and are not suitable.
