Three things to look for when buying a Brix Refractometer

Brix Refractometers are used to measure sugar within a substance. Used most commonly in the food and beverage industry, they give a wealth of information at the touch of a button.

There is a huge variety of Brix Refractometers on the market. This article steps out a process you can apply to find the perfect Brix Refractometer for your needs. We also provide some product examples to help guide you on the way.

About Brix Refractometers

A Brix Refractometer measures the level of sucrose within a sample through refraction. The higher the amount of dissolved or suspended sugar (sucrose) within a sample, the higher the refractive index will be. The refractive index directly correlates to a Brix Percentage, which is the weight percentage of sucrose present in the sample.

(For a deep dive into how Brix Refractometers work read our article What is a Brix Refractometer, and how do they work?)

Why use a Brix Refractometer?

From the farm gate to the supermarket or bottleshop, Brix Refractometers play an important role. Using the food and beverage industries as prime examples, the sucrose level of food or drink gives a good indication of the taste, quality, and nutritional density of the food. It can even provide a guide to the potential of ingredients to produce alcohol in wine and beer.

So how do you select the best meter for your application(s)?

Three key criteria to help you select a Brix Refractometer

  • 1.Automatic Temperature Compensation

Automatic Temperature Compensation (ATC) is a key feature you must have in a Brix Refractometer if you need quick and accurate results. The measurement of the Brix Percentage is affected by temperature. For example; in a 10°Brix sucrose solution, ±1°c of change can cause the Brix reading to shift by ±0.06°Bx!

Without ATC, you need to wait for both your sample and your meter to reach 20 degrees Celsius to obtain an accurate reading. Alternatively, you need to calculate a temperature adjustment manually. Any way you look at it, it will take more time, a luxury you might not have in a fast-moving manufacturing environment, or you could make costly mistakes that you could easily avoid with the right equipment.

The bottom-line? A Brix Refractometer with ATC will automatically compensate for the temperature to give you fast, accurate results - too easy!

  • 2.Measurement Range

Before selecting your Brix Refractometer, you need to know the Brix measurement range of the food or beverage you will be measuring. Manufacturers design these instruments either for specific applications, or a wide variety of applications. If your application is very specialised, a narrow range may suffice. If your products vary significantly, and you want a single meter to do the work, invest in a refractometer with a wide Brix measurement range.

What’s the take-home? Filtering your selection by the Brix measurement range will save you time and can also save you money.

  • 3.Accuracy

Having narrowed down your selection to devices with ATC, that comfortably covers your Brix measurement range, the last specification you need to match is accuracy. In situations where Brix is vital to your product quality control, you will need a highly accurate meter. In less critical circumstances, a broader accuracy range may be acceptable.
