The 

HI96812

 

Digital Wine Refractometer is rugged portable, water resistant 

devices that benefit from Hanna Instruments’ years of experience as a 
manufacturer of analytical instruments. Hanna Instruments offers five related 
wine refractometers to fill the differing requirements found in the industry. 
All are equally valid ways to measure the sugar content of grape or must 
samples in the field or winery.
The 

HI96812

 is optical instruments that are based on the measurement of 

the refractive index of a solution. The measurement of refractive index is 
simple and quick and provides the vintner a standard accepted method for 
sugar content analysis. Samples are measured after a simple user calibration 
with deionized or distilled water. Within seconds the instrument measures 
the refractive index of the grape. These digital refractometers eliminate the 
uncertainty associated with mechanical refractometers and are easily por‑
table for measurements in the field. Temperature (in °C or °F) is displayed 
simultaneously with the measurement on the large dual level display along 
with icons for Low Power and other helpful message codes.
Key features include:
•  Dual‑level LCD
•  Automatic Temperature Compensation (ATC)
•  Easy setup and storage
•  Battery operation with Low Power indicator (BEPS)
•  Automatically turns off after 3 minutes of non‑use
•  Single‑point calibration with distilled or deionized water
•  Waterproof models offers IP65 waterproof protection
•  Quick, precise results readings are displayed in approximately 1.5 seconds
•  Small sample size as small as 2 metric drops.
