HI96821 Digital Refractometer for Measuring Sodium Chloride in Food
Learn About the Hanna Instruments Sodium Chloride Refractometer for Food Analysis HI96821
- Sample size as small as 2 metric drops (100 μl)
- Sealed stainless steel well with high-grade optical prism made of flint glass
- Fast 1.5 second response time for temperature compensated readings
Details
The HI96821 portable refractometer converts the refractive index of a food sample to g/100 g, g/100 mL, specific gravity and °Baume. These conversions are based on internationally recognized references for unit conversion. The HI96821 is ideal for the analysis of salad dressings, cheeses, condiments, canned and jarred foods, soups, brines and whey. The HI96821 is an easy to use tool for measuring sodium chloride in foods, whether on the production line or in the lab.
- Designed for sodium chloride analysis in foods
- Automatic Temperature Compensation
- High accuracy measurements in g/100 g, g/100 mL, specific gravity and °Baume
Making a Standard NaCl Solution (g/100 g)
To make an NaCl Solution, follow the procedure below:
- Place container (such as a glass vial or dropper bottle that has a cover) on an analytical balance.
- Tare the balance.
- Weigh out X grams of high purity dried Sodium Chloride (CAS #: 7647-14-5: MW 58.44) directly into a beaker
- Add distilled or deionized water to the beaker so the total weight of the solution is 100g.
| NaCl (g) | Water (g) | Total (g) |
| 10.000 | 90.000 |
100.000 |
Refractive Index
The HI96821 takes measurements based on a sample’s refractive index. Refractive index is a measurement of how light behaves as it passes through the sample. Depending on the sample’s composition, light will refract and reflect differently. By measuring this activity 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 HI96821 uses an LED light, prism and lens to make measurement possible.
Variations in temperature will affect the accuracy of refractometry readings, so the use of temperature compensation is highly recommended for reliable results. The HI96821 contains a built-in temperature sensor and is programmed with temperature compensation algorithms in accordance with internationally recognized references which vary based on the parameter being measured.

The HI96816 Digital Wine Refractometer has a potential alcohol curve is based on the tables found in the European Economic Community Commission Regulation No 2676/90 of 17 September 1990, Determining Community Methods for the Analysis of Wine and International Organization of Vine and Wine (OIV). The potential alcohol curve is based on the following equation:
Potential alcohol %V/V = g/L of Sugar / 16.83
