Refractometer 0-32% Brix ATC w/ Hardcase and Tools

A refractometer is a laboratory or field instrument used to measure the refractive index of a substance. This physical value determines how much light bends (refracts) when it passes through a liquid or solution, allowing users to instantly calculate the concentration of dissolved substances. When light enters a liquid, its speed changes, causing it to bend. Refractometers measure this specific angle of deviation (based on Snell's Law). As the concentration of a solute (like sugar or salt) increases, the light bends more. The instrument projects this boundary line onto a calibrated internal scale for the user to read. Product Specs:

• 0-32% Brix Scale - Easy to Read!
• Accurate to +/- 0.20% Brix
• Scale Divisions: 0.20%
• Automatic Temperature Compensation (ATC) Range 50-86'F (10-30'C)
• Sturdy design, made of durable machined Aluminum, not "carbon" plastic - 50% heavier than the soft case units
• Includes: A foam-lined Gray Plastic Hard Case, a plastic transfer pipette for dropping test fluids onto the prism (never dip the refractometer into the test fluid!), a mini screwdriver for scale calibration, and a Users Guide.

Applications

• Food & Beverage: Measuring the Brix scale (sugar content) in harvest fruits, juices, honey, wine, and beer brewing.
• Aquariums & Marine Biology: Checking water salinity levels and specific gravity in reef tanks.
• Automotive & Industrial: Testing the concentration of engine coolants, machine anti-freeze, and diesel exhaust fluids.
• Medical & Veterinary: Analyzing blood plasma protein levels and urine specific gravity.

How to Use and Calibrate

1. Lift the plate: Open the clear daylight cover plate over the main prism.
2. Apply fluid: Place 2–3 drops of distilled water onto the prism surface.
3. Zero-out (Calibrate): Close the plate, look through the lens, and turn the calibration screw until the boundary line rests exactly at zero.
4. Test sample: Wipe the prism clean, apply your sample fluid, close the plate, and read the scale interface.
5. Clean immediately: Clean thoroughly with a soft cloth after use to prevent corrosion or sticky residue.
