Force and mechanical measuring equipment
The HI96816 is a rugged, portable digital refractometer designed to measure the potential alcohol concentration (% V/V) of wine, fruit juices according to European Economic Community Commission Regulation No. 2676/90.
– High accuracy 0.2% V/V potential alcohol
(Alcohol content is calculated based on sugar content)
– Scale 4.9 to 56.8% Potential alcohol V/V
– Small sample size, about 2 drops of solution (0.1 mL)
– Simple and easy calibration with just 1 key
– Fast, accurate measurement in 1.5 seconds
The HI96816 Digital Wine Refractometer has a potential alcohol curve based on the tables found in the European Economic Community Commission Regulation No 2676/90 of 17 September 1990, Defining Community Methods for the Analysis of Wine and the International Wine Organization (OIV). The potential alcohol curve is based on the following equation:
% V/V Potential Alcohol = g/L of Sugar/16.83
+ Designed to determine potential alcohol in wine and juice
+ Automatic temperature compensation
+ Range 4.9 to 56.8% V/V with accuracy ±0.2% V/V
The accuracy of the HI96816 can be checked by preparing a % Brix standard solution. After calibration, the 25% Brix solution is placed in the measurement cell and the key READ is pressed repeatedly until the % Brix value is displayed on the main LCD. The HI96816 contains a built-in temperature sensor and is programmed with temperature compensation algorithms per the ICUMSA Methods Book Standard for one percent by weight sucrose.
Calibrate with distilled or deionized water
AUTOMATIC TEMPERATURE COMPENSATION (ATC)
Measurement results are automatically compensated for temperature
MULTI-LEVEL LCD SCREEN
LCD display shows measurement value and temperature at the same time
Easy to clean and corrosion resistant
BATTERY INDICATOR
Remaining battery level will be displayed when power on and low battery warning
AUTO SHUT OFF
The machine will automatically turn off after 3 minutes of non-use.
IP65 WATERPROOF
ABS plastic shell prevents dust and moisture
HOW TO MAKE STANDARD SUCROSE SOLUTION
Place the container (such as a glass jar or dropper bottle with a cap) on an analytical balance.
Tare
Weigh X grams of high purity sucrose (CAS #: 57-50-1) directly into the container.
Add distilled or deionized water to the container so that the total weight of the solution is 100g.
Note: The solution on 65% needs to be stirred or shaken vigorously and the water heated to about 40oC. Remove the solution from the tank when the glucose has completely dissolved and allow to cool before use.
REFRGUSTING INDEX
The HI96816 allows for measurements based on a sample’s refractive index. Refractive index is a measure of how light behaves as it passes through a sample. Depending on the composition of the sample, light will refract and reflect differently. By measuring this with a linear image sensor, the sample’s refractive index can be assessed and used to determine its physical properties such as concentration and density. In addition to the linear image sensor, the HI96816 uses an LED light, prism, and lens to make measurement possible.
Fluctuations in temperature will affect the accuracy of refractive index readings, so the use of temperature compensation is highly recommended for reliable results. The HI96816 contains a built-in temperature sensor and is programmed with temperature compensation algorithms in accordance with European Economic Community Commission Regulation No. 2676/90 of 17 September 1990, Defining Community Methods for the Analysis of Wine and the International Organization of Wine and Spirits (OIV).
