Refrectometer 0-32 (Milk)

Refractometer ATC 0–32% Brix Range

Supplier: Mian & Sons Scientific Traders — Faisalabad, Pakistan

Overview

The handheld Refractometer ATC 0–32% Brix is a precision optical instrument used to measure the concentration of soluble solids (primarily sugar) in aqueous solutions. Its simple-to-use optical design, fast response and Automatic Temperature Compensation (ATC) make it a standard tool for quality control in food & beverage, agriculture, brewing, and laboratory environments.

Key Benefits

  • • Portable, pocket-sized and ideal for field use
  • • Quick, reliable readings with only a few drops of sample
  • • ATC minimizes temperature-related error (common in manual refractometers)
  • • Low maintenance and long service life with basic care
  • • Cost-effective solution for routine Brix measurement

Principle of Operation

A refractometer measures the refractive index of a liquid sample. When light passes from the prism into the sample it changes direction (refracts). The degree of refraction depends on the solute concentration; the instrument converts refractive index to a Brix percentage scale. The ATC mechanism compensates for changes in ambient temperature so readings reflect true concentration.

Common Applications

Food & Beverage

  • ✔️ Measure sugar content in juices, syrups, honey and soft drinks
  • ✔️ Control consistency of jams, jellies and confectionery syrups
  • ✔️ Monitor finished product quality in beverage plants

Agriculture & Horticulture

  • ✔️ Assess fruit ripeness (grapes, mangoes, apples, citrus)
  • ✔️ Monitor sap and nutrient solutions for hydroponics
  • ✔️ Evaluate crop quality before harvest and for export grading

Brewing & Distilling

  • ✔️ Measure wort concentration and fermentation progress
  • ✔️ Control sugar additions and alcohol yield estimation

Laboratory & Education

  • ✔️ Routine concentration checks in research and QC labs
  • ✔️ Demonstrations in teaching laboratories—optics and solution chemistry

Industrial

  • ✔️ Check concentration in coolants, antifreeze, and industrial fluids where Brix or refractive index correlates with concentration

How to Use — Step-by-Step

  1. Calibrate the refractometer with distilled (or deionized) water: place a drop on the prism, close the cover, view scale and adjust calibration screw until reading is zero (or manufacturer-specified value).
  2. Clean the prism and wipe dry before testing the sample.
  3. Place 2–3 drops of the sample on the prism surface, avoiding air bubbles.
  4. Close the cover plate gently to spread the sample into a thin film.
  5. Point the eyepiece toward a natural light source and look through the eyepiece.
  6. Read the Brix value at the boundary line between light and dark fields; record the result.
  7. Clean the prism immediately after use to prevent residue build-up.

Tip: For viscous samples (honey, syrups), warm slightly or dilute following standard lab practice and apply consistently to maintain reproducible results.

Calibration & Accuracy

Regular calibration ensures accuracy. Most ATC handheld refractometers require single-point calibration using distilled water (0% Brix) or standard calibration fluids (e.g., 10% Brix solution). For critical work, verify calibration with a certified reference solution and document calibration records.

  • • Calibrate at ambient temperature within the device ATC range for best results.
  • • Recalibrate if the device is dropped, exposed to shock, or after extended storage.
  • • Keep records of calibration, including date, operator and reference used.

Maintenance & Care

  • • Clean prism after every use with distilled water and a soft, lint-free cloth.
  • • Do not use abrasive cleaners or hard brushes on the prism surface.
  • • Store in the supplied protective case to avoid dust and mechanical damage.
  • • Avoid exposing the instrument to extreme heat, direct sunlight for prolonged periods, or corrosive chemicals.
  • • Replace or repair damaged eyepieces, prisms or seals through authorized service to maintain accuracy.

Advantages vs Digital Refractometers

Handheld optical ATC refractometers provide cost-effective, rugged performance for many routine tasks. They are battery-free, simple to operate, and require minimal maintenance. Digital refractometers offer automatic readout, higher precision and data logging—however they are more expensive, require batteries and are less rugged in some cases.

  • • Optical ATC Refractometer: low cost, no power needed, rugged, ideal for field work.
  • • Digital Refractometer: advanced features, higher precision, data export (choose if your application requires traceable digital records).

Buying Considerations

  • • Select ATC range that matches your working temperatures—confirm device ATC span.
  • • Verify accuracy and resolution meet your QC requirements (±0.2% typical for quality optical models).
  • • For sticky/viscous samples, consider models with larger prism area or consult dilution procedures.
  • • If required, ask for manufacturer calibration certificate or traceable reference standards.
  • • Consider digital models if you need data logging or network integration.
