Hanna HI96801 Digital Refractometer for Brix Measurement in Food

Description

Comprehensive and Detailed Introduction to the Hanna HI96801

The Hanna Instruments company, with years of experience in the field of analytical equipment, has introduced the rugged, portable, and water-resistant digital refractometer, the HI96801. This refractometer determines the percentage Brix (sugar concentration) in aqueous solutions by measuring the refractive index. The measurement process with this device is very simple and fast. After a quick calibration using deionized or distilled water, the instrument measures the sample’s refractive index in a matter of seconds and converts it to % Brix concentration units. This device eliminates the uncertainty associated with mechanical refractometers and, due to its portability, is easily used for measurements in the field.

The measurement and temperature compensation methods of this product are based on the principles recommended in the ICUMSA Methods Book (International Commission for Uniform Methods of Sugar Analysis). The sample temperature is displayed simultaneously with the measurement result on a large dual-level display, which also includes icons for low battery and other helpful messages. The device’s design is user-friendly and features a dual-level LCD, Automatic Temperature Compensation (ATC), and an automatic shut-off feature after 3 minutes of non-use. With an accuracy of ±0.2% Brix, this device is an excellent choice for measuring sugar content in food products.

Extensive Applications in Industry and Laboratory

The HI96801 is specifically designed for sugar analysis in food products and has a wide range of applications. This refractometer is ideal for the accurate analysis of sugar content in various fruits, energy drinks, puddings, soy milk, juices, jams, marmalades, honey, soups, jellies, tofu, and condiments. Its ability to measure very small samples, as little as 100 μL, makes it suitable for any size food laboratory, from small to large. Furthermore, thanks to its rugged, waterproof construction with an IP65 rating, the device can be used with complete confidence in field conditions as well.

Key Differences and Outstanding Advantages

One of the main advantages of the HI96801 is the elimination of uncertainties associated with mechanical refractometers. With this device, the measurement is based on the sample’s refractive index, which is a fundamental optical characteristic. Using a linear image sensor, the device determines the critical angle at which light is no longer refracted through the sample. This value is then converted to Brix sucrose concentration. This digital process ensures accurate and repeatable results. Also, the Automatic Temperature Compensation (ATC) ensures that temperature variations do not affect the accuracy of the results.

Product Structure and Engineering Design

The HI96801 is constructed with a stainless steel sample well and a high-grade optical prism made of flint glass, which makes it very easy to clean. This durable construction, along with the IP65-rated ABS plastic casing, makes the device suitable for use in both laboratory and field conditions. The device operates on a 9-volt battery and has a battery life of up to 5000 measurements. It also features an automatic shut-off function after 3 minutes of inactivity to conserve battery life.

How it Works and the Measurement Process

The HI96801 operates by measuring the sample’s refractive index. The refractive index is a measure of how light behaves as it passes through a substance. 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. The device uses a yellow LED as the light source, a prism, and a lens to make measurement possible.

The Importance and Impact of Ambient Temperature on Results

Temperature variations affect the density of solutions, so in digital refractometry, the use of temperature compensation is necessary to achieve accurate results. The HI96801 has a built-in temperature sensor and is programmed with temperature compensation algorithms in accordance with the ICUMSA Methods Book, which compensates the results for a percent by weight sucrose solution. This feature ensures that the measured results are always accurate and reliable, regardless of ambient temperature fluctuations.

Guide to Preparing a Standard % Brix Solution

To make a standard % Brix solution, follow the procedure below: First, place a container (such as a glass vial or dropper bottle that has a cover) on an analytical balance. Then tare the balance. To prepare an X% BRIX solution, weigh out X grams of high-purity sucrose (CAS #: 57-50-1) directly into the container. Finally, add distilled or deionized water to the container so that the total weight of the solution is 100g. For solutions above 60% Brix, it may be necessary to stir or shake the solution vigorously and heat it in a water bath to approximately 40°C (104°F). Once the sucrose has dissolved, allow the solution to cool before use.
