Measure soluble solids and monitor sugar concentration with the AQUILA PRO Digital Brix Refractometer. Designed for routine testing in food production, beverage manufacturing, laboratories and small-scale processing operations, this handheld digital refractometer provides a simple way to check Brix levels without the interpretation required by a traditional optical refractometer.

With a 0–55% Brix measuring range, ±0.2% Brix accuracy and 0.1% resolution, the AQUILA PRO is a practical choice for businesses and individuals who need quick, repeatable measurements to monitor product consistency, evaluate ingredient concentrations and check production batches.

Automatic Temperature Compensation (ATC) helps account for temperature variations within the instrument’s specified operating range of 50°F to 104°F (10°C to 40°C). The digital display makes readings easy to view, while the rechargeable lithium battery and USB charging provide convenient operation without routine battery replacement.

Whether you are checking fruit juice, preparing syrups, monitoring jam production or measuring sugar solutions in a food processing environment, the AQUILA PRO provides an accessible and economical way to incorporate Brix testing into your quality control routine.

Who Should Use the AQUILA PRO Digital Brix Refractometer?

A fast, affordable digital Brix meter for anyone who needs quick, repeatable readings from 0-55% Brix.

• Food and beverage producers: Check juices, juice concentrates, low-sugar sauces and syrups, and soda fountain syrup ratios to keep every batch consistent.
• Jam, jelly and preserve makers: Track concentration as fruit cooks down and water evaporates.
• Growers and produce buyers: Test the juice from fruits and vegetables to compare sugar content across crops, varieties, or harvest dates.
• Dairy and livestock operations: Use Brix readings on colostrum and milk as a quick on-farm check.
• Machine shops and CNC operators: Monitor coolant concentration by Brix. Convert readings with your coolant manufacturer's factor, and note that tramp oils and contamination can affect results.
• Homebrewers, winemakers and mead makers: Measure must or wort Brix before fermentation. Alcohol skews readings afterward, so use it pre-fermentation only.
• Bakers, candy makers and commercial kitchens: Verify sugar solutions and liquid ingredients within the 0-55% range. Candy work above 55% needs a higher-range model.
• QC technicians, schools and labs: An economical handheld instrument for routine soluble-solids checks.

Recommended Applications

Juice, Beverage and Soda Fountain Checks
Measure Brix in fruit juices, concentrates, and mixed drinks to compare batches and confirm blend or dilution targets. For soda fountains, a quick Brix reading helps confirm the syrup-to-water ratio.

Jam, Jelly and Preserves
Track concentration as fruit cooks down and water evaporates, so every batch finishes at the same target Brix.

Fruit and Vegetable Testing
Press a few drops of juice from fruit or vegetables to compare sugar content across varieties, harvest dates, or fields. Filter out pulp so the sample is clear and the readings are consistent.

Colostrum and Milk
Brix is a common on-farm indicator of colostrum quality, and many dairy guidelines use around 22% Brix as a benchmark for bovine colostrum. Check the guidance for your species and herd program, and clean the chamber right after each sample.

CNC and Machining Coolant
Brix readings help you monitor coolant concentration and catch it drifting before it affects tool life or finish. Multiply the reading by your coolant manufacturer's refractometer factor to get concentration. Tramp oils and contamination can affect results.

Homebrewing, Winemaking and Mead
Measure the Brix of your must or wort before fermentation to track sugar content and plan your batch. Once fermentation begins, alcohol skews readings, so use this meter pre-fermentation only.

Sauces, Syrups and Sugar Solutions
Verify simple syrups, dressings, and low-sugar sauces. Salt, acids, fats, and suspended solids can shift readings, so compare against your own recipe benchmarks.

Candy and Confectionery
Check sugar solutions and liquid ingredients within the 0-55% range. Processes above 55% Brix need a higher-range refractometer.

Key Features and Benefits

• Wide 0–55% Brix range: Covers many routine sugar concentration and soluble-solids testing applications.
• ±0.2% Brix accuracy: Suitable for general-purpose concentration checks where this accuracy meets the user’s requirements.
• 0.1% Brix resolution: Displays readings in convenient 0.1% increments.
• Automatic Temperature Compensation: Compensates for temperature effects within the specified operating range of 50°F to 104°F (10°C to 40°C).
• Simple digital operation: View the measured value directly on the display without visually interpreting an optical scale.
• Rechargeable lithium battery: A built-in 750 mAh battery supports convenient portable use.
• USB charging: Recharge the instrument without purchasing disposable batteries.
• Washable sample chamber: The sample chamber can be rinsed under running water for easier cleanup. Keep the instrument body and charging port dry, and never submerge the complete instrument.
• Portable design: Convenient for use at a production bench, in a small laboratory or during field sampling.

Technical Specifications

How to Use a Digital Brix Refractometer

1. Calibrate the instrument. Follow the manufacturer’s instructions and use distilled water to establish a zero-Brix reading before testing.
2. Prepare the sample. Use a representative sample that is sufficiently liquid and free of large particles or other material that could interfere with measurement.
3. Apply the sample. Place enough sample into the measuring chamber to cover the sensing surface as directed in the manual.
4. Take the reading. Close the sample cover as applicable and activate the measurement function.
5. Clean the chamber. Remove the sample and clean the measuring surface between tests to prevent carryover and contamination.
6. Verify consistency. For critical production decisions, check calibration regularly and compare results with a validated method or reference instrument.

For the most consistent results, allow samples to reach a suitable temperature within the instrument’s operating range and follow the manufacturer’s sampling and cleaning instructions.

Understanding Brix Measurements

Brix is commonly used to express the concentration of dissolved solids in an aqueous solution as a sucrose-equivalent percentage. For a pure sucrose-water solution, 20° Brix corresponds approximately to 20 grams of sucrose per 100 grams of solution.

In real food products, a Brix reading is an optical estimate of soluble-solids concentration based on refractive index. Acids, salts, other sugars and dissolved ingredients can affect the result. A Brix reading is not necessarily the same as the actual sugar percentage in a complex food mixture.

For applications such as finished-product labeling, regulatory compliance or critical process control, confirm that Brix is the correct measurement and validate the method for the specific product.

Is the AQUILA PRO 0–55% Brix Refractometer Right for You?

Choose the AQUILA PRO when you need an affordable, rechargeable digital Brix refractometer for routine measurements of suitable aqueous samples, with a broad working range and straightforward operation.

If your application requires a specialized scale, tighter measurement tolerances, higher Brix levels, or validated results for a specific formulation, a dedicated refractometer may be the better choice. Alcohol-containing samples, for example, can produce misleading sugar estimates when measured with a standard Brix scale after fermentation.

Frequently Asked Questions About the AQUILA PRO Digital Brix Refractometer 

Can I test colostrum or milk?
Yes, as a quick on-farm check. Brix is commonly used to gauge colostrum quality, and readings are best compared against the benchmarks your veterinarian or dairy program uses. Rinse and dry the chamber after every sample.

Can I test fruit and vegetables?
Yes. Squeeze or press a few drops of juice, strain out pulp, and read the Brix. Use it to compare ripeness and sugar content across samples.

Can I measure honey or maple syrup?
No. Honey is around 80% Brix and maple syrup around 66%, both above this meter's 0-55% range. You'll need a high-range refractometer for those.

Can I use it for coffee?
Not recommended. Filter coffee is only about 1-1.5% TDS, so ±0.2% precision is too coarse to tell good brews from weak ones. A coffee-specific refractometer is the better tool.
