But First, how do Refractometers Measure?Ā
Refractometers work by using the interaction of light and refraction. The core principle is the refractive index, a measure of how much light bends as it passes from one substance to another. The instrument measures this bending to determine a reading.Ā Available in manual or digital versions,Ā providingĀ readings via an eyepiece orĀ digital display.
Manual refractometersĀ use an external light source that passes through the sample, projecting a reading onto an internal scale viewed through an eyepiece.
Digital refractometersĀ offer enhanced user-friendliness with an integrated light source and clear digital readout. Instead of light passing through the sample, these meters measure the reflectivity of light from the sample, which is then translated into a direct measurement.
While both types of meters differ in their measurement method, they fundamentally utilise the interaction of light and refraction to determine their readings.

Sugar Refractometer 0-32% Brix | IC300001
The Sper Scientific IC300001 manual refractometer represents ease of use; simply apply a sample to the sample area, ensuring an even spread. Then, view your Brix reading clearly through the eyepiece. This particular refractometer is designed for the food and beverage industries, measuring sugar content between 0-32%.
Other Features include,
- Light-weight and portable for easy measurements
- Easily calibrated with distilled water
- Focusing eye piece, ensuring easy readability of measurements

Digital Hand-held Pocket Refractometer | IC-PAL-3
Digital refractometers operate on a similar, yet distinct, principle of light interaction. They are exceptionally easy to clean with a simple wipe and rinse of the sample area. Instead of relying on an external light source like sunlight, digital refractometers feature an integrated light source. This integrated light source shines onto the sample, measuring the light reflected from it rather than light passing through. These advantages include effortless cleaning, a clear digital measurement display, and portability for field use.
Other features,
- Wide measurement range, 0.0-93%
- Perfect for food and beverage use
- NFC enabled for mobile data transfer

Digital Hand-held Pocket Coffee Refractometer | IC-PAL-Coffee
The unique refractive index of each sample allows for highly specific and precise testing across various media. Take, for instance, the IC-PAL-Coffee ā a specialized tool for baristas and coffee producers that precisely measures the Brix (sugar content) and Total Dissolved Solids (TDS) of coffee and espresso. This demonstrates how refractometers, with their convenient and accurate testing methods, are expanding into diverse applications.
Key features:
- Dual scale of Brix and TDS
- Sample volume of 2 to 3 drops
- IP65 Water Resistant
Pocket IR Brix Meter (Kiwi) | PAL-HIKARI-8
Refractometers are popular within the fruit production industry. Their widespread popularity stems from the renowned convenience they offer. The PAL-HIKARI-8, for instance, streamlines Kiwi fruit Brix content measurement. There's no need for cutting or squeezing; simply place the fruit on the meter for a quick, accurate test. *Ensure no gaps between the fruit and seal*.Ā A wider range of models areĀ also available, enabling on-site Brix content testing across various fruit types.
Key features:
- Easy to use with no need to cut samples
- Measurement range of 6-20%
- Speciality meter designed for kiwi fruits
Honey Refractometer | IC-PAL-22S
Refractometers aren't exclusively for measuring Brix/sugar content. A key measurement in honey production is the water content of honey. IC-PAL-22S transforms this 'sticky business' into a easy-to-use handheld meter. It's easy-to-clean testing area allows for quick and accurate field readings by simply placing a honey sample on the prism. This ensures simple and efficient testing throughout the day.
Key features:
- Hand held unit for testing anywhere
- Measures water content of honey easily with digital display
- Quick 3 second measurement time
