Handheld wine-testing instrument that measures grape sugar and estimates potential alcohol with straightforward optical readings. Confident harvest decisions and clearer fermentation planning for small-scale growers. Is the HHTEC Winemaker Refractometer the best fit for hobbyists and vineyard owners who need quick field checks?
⚡ At a Glance
- • Measurement Accuracy: Brix 0-40% and alcohol 0-25% with 0.2% resolution for precise readings
- • Best for: Winegrowers and hobbyist winemakers monitoring harvest timing and fermentation potential
- • Not ideal for: Laboratories or users requiring digital logging and lab-grade instruments
Optical refractometer reads Brix and shows corresponding alcohol potential. Simple calibration and ATC make field checks repeatable and straightforward.
Predict Potential Alcohol - thanks to Brix and alcohol scales
Direct optical scales cover Brix 0-40% and alcohol 0-25% with a reported resolution of 0.2%. Readings appear against a sharp blue-white dividing line visible through an adjustable eyepiece.
Quickly estimate likely alcohol by volume from grape juice measurements, helping decide harvest timing and blending choices. Readings are fast enough for spot checks across a vineyard.
Consistent Readings in Changing Temperatures - thanks to automatic temperature compensation
Automatic temperature compensation works between 10 °C and 30 °C, while zero calibration uses distilled water at 20 °C. Calibration and ATC remove manual correction for common field conditions.
Obtain comparable measurements across different times of day without complex maths. Repeatable results make it easier to track ripeness trends over a season.
Field-Friendly Checks - thanks to simple sample method and clear optics
Apply two to three drops of sample to the main prism, close the cover plate and view the scale through the eyepiece; adjustable focus sharpens the dividing line for easier reading.
Carry out rapid checks between rows with minimal kit and little training. Portable operation suits spot sampling and routine vineyard monitoring.
