Description
The Hanna HI96811 is a portable, rugged digital refractometer specifically designed for measuring sugar content in grape juice, must, and other wine-related samples. It converts the refractive index of a sample to % Brix (a measure of soluble solids, primarily sugars) with high precision, making it an essential tool for winemakers, brewers, and food professionals. The HI96811 Unlike traditional mechanical refractometers, it eliminates subjective readings and provides fast,temperature-compensated results in the field or lab. Hanna HI96811 Digital Refractometer
Key Features
- Easy Operation: Only two buttons—one for calibration (using distilled or deionized water) and one for measurement. Results display in 1.5 seconds.
- Small Sample Size: Requires just 2 metric drops (100 μl) for testing.
- Temperature Compensation: Built-in sensor automatically compensates for variations between 10–40°C (50–104°F) per ICUMSA standards for sucrose solutions.
- Durable Design: Water-resistant ABS plastic casing, sealed flint glass prism, and stainless steel sample well for easy cleaning (wipe with a soft cloth).
- Optical System: Uses an LED light, prism, and lens with a linear image sensor for reliable refractive index detection.
- Battery Life: Powered by a 9V battery (included), lasting approximately 5,000 readings.
