GENERAL DESCRIPTION
The
HI 96811
Digital Wine Refractometer is rugged portable, water
resistant devices that benefit from Hanna’s years of experience as a
manufacturer of analytical instruments. Hanna 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
HI 96811
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 portable 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.
