Handheld Refractometer for Accurate Sugar Content Measurement
Handheld Refractometer for Accurate Sugar Content Measurement
No se pudo cargar la disponibilidad de retiro
Handheld Brix refractometer with automatic temperature compensation (ATC). Measures sugar content 0-32% in fruit juice, honey, maple syrup, beer wort, jam, wine must, and any sugary liquid. Zero battery required, calibrates instantly with distilled water, ATC keeps readings accurate across 50-86 °F (10-30 °C).
What this refractometer is for
- Home brewing + winemaking — measure original gravity of wort or must; track fermentation progress
- Fruit + honey producers — check ripeness, jam setting point, honey moisture-adjacent sugar content
- Maple syrup — hit the 66 °Brix mark for USDA Grade A
- Agriculture + gardening — measure crop sugar levels as a proxy for ripeness and nutrient density
- Education — food-science labs, biology and chemistry teaching demos
How to use
- Open the daylight plate. Place 2-3 drops of your sample on the prism using the included pipette.
- Close the plate and hold the refractometer up to a light source (window or lamp).
- Look through the eyepiece — read the Brix percentage where the blue/white boundary line crosses the scale.
- Wipe the prism clean between samples. Recalibrate with distilled water occasionally.

Frequently asked questions
Does it work with alcoholic drinks (beer, wine)?
Yes for wort and must (pre-fermentation). Post-fermentation the alcohol interferes with the reading — use a correction chart or a hydrometer for final gravity if you need alcohol content.
Do I need to calibrate before every use?
A daily zero-point check with distilled water is best practice. Adjust with the included screwdriver if the zero line drifts.
What if I need a higher Brix range for maple syrup finishing?
This unit tops out at 32 %. For finishing maple syrup at 66 °Brix you'll need a higher-range refractometer (0-90 or 58-92 Brix scale). Contact us and we'll help you pick the right one.
Does it need batteries?
No. It's a fully optical instrument — hold it up to any bright light source.
Is the case included?
Yes. The refractometer, cleaning cloth, calibration screwdriver, pipettes, and instructions all fit in the included plastic case.
