Brix meter – Kyoto Electronics Manufacturing Co. Ltd., Japan

Kyoto Electronics Manufacturing Co. Ltd. manufacture high-quality portable analytical instruments which find application in the food and beverages industry. One such popular instrument is the portable digital Brix meter, BX-1.

The BX-1 has been found to be a good fit for laboratory and production environments because of its broad measuring range and compact design. It can measure the Brix % of liquids between 0 and 85 with a resolution of 0.1 Brix %. To measure the Brix % of a liquid, you just need to place a few drops of the liquid on the measuring prism, and you will get a value on the digital display within a couple of seconds. Since Brix is a temperature-dependent parameter, the BX-1 Brix meter has a built-in algorithm for automatic temperature compensation for liquids which are between 10 and 75 deg Celsius. In addition to its sleek build, automatic temperature compensation is one of the features which makes it the preferred option in quality control (QC) and research labs.

What is Brix?

In simple terms, Brix is the quantity of sucrose (in grams) present in 100 grams of the sample. The formula for calculating Brix can be written as

1-degree Brix = 1 gm of sucrose / 100 gms of sample

One-degree Brix is the same as 1% Brix which is the unit displayed by mostBrix meters. The resolution could vary based on the instrument used.

Brix is a widely standardized parameter, especially in the quality-control departments of the food and beverages industry. By maintaining the Brix value in juices, uniform sweetness is ascertained. The Brix value is preferred as a reference over density or refractive index because it is simpler to read. For example, it is easier to check if the sample has a Brix value of 8.5 deg than checking for a refractive index of 1.3458.

Methods of measuring Brix

There are different ways in which the sucrose content in a liquid sample can be measured. The two most common methods are by using density or refractometry. For pure sucrose, both methods will deliver the same result. However, for other samples, the results will vary based on the method adopted.

It is important to note is that there is no one right or wrong way. The means to obtain Brix simply depends on the standards which have been established in each lab.

Brix by density

Brix can be calculated by means of determining the density of the sample since there is a direct relation between density and deg Brix. Once the density is calculated, it can be converted to Brix based on table 109 of NBS circular 440.

Brix by refractometry

As mentioned earlier, it is also possible to arrive at the Brix value from the refractive index of a liquid sample since there is a direct relation between the two parameters.

If you are still confused about which instrument to use for finding the Brix % of your samples, we recommend using a refractometry-based Brix meter since it is the standard in most laboratories.

How does the BX-1 Brix meter work?

The BX-1 works based on the principle of refraction. When a ray of light travels from one medium to another having different optical density, it changes direction. This difference in angle is called angle of refraction.

The BX-1 measures the refraction angle and correlates it with refractive index, thereby arriving at a Brix % value. This conversion is well-established in the industry.

Brix % depends on the wavelength of the incident ray and also the temperature of the sample being measured. To counter the variance due to wavelength, the BX-1 measures Brix % at a standardized wavelength.

How does the BX-1 Brix meter work?

Brix meters find a wide variety of applications in industries such as food and beverages, agricultural, and chemical companies. The BX-1 can be used to assess the quality of a variety of liquids such as fruit juices, carbonated drinks, wine, milk, oil, chemicals, and a lot more.

The following is a list of Brix range of commonly assessed liquids:
