Refractometers

About Refractometers

Refractometers are optical or digital instruments used to measure refractive index, thereby determining the concentration of dissolved substances such as sugar content (Brix) or salinity in liquid and semi-solid samples. They are widely used in quality control for food, beverages, agriculture, as well as industrial solutions like metal cutting fluids.

When choosing a refractometer, users need to clearly determine the sample type and analytical parameters to be measured, from common samples such as juice, jam, and sauce to specific samples with high fat content or high viscosity. Depending on the working environment in the field or in the laboratory, buyers can choose between traditional handheld optical refractometers or compact digital refractometers. Currently, Hoa Viet supplies refractometers from the Atago (Japan) brand with a diverse product range, specifically tailored to each sample testing purpose.

How do traditional optical refractometers and digital refractometers differ?

Optical refractometers operate by observing the boundary line through an eyepiece under a light source to read the result. Digital refractometers use optical sensors to automatically convert signals and display measured values directly in digital form, minimizing human reading errors.

Which brands of refractometers does Hoa Viet provide?

Hoa Viet currently distributes refractometers from the Japanese brand Atago. The product line includes both MASTER series analog instruments and PAL series digital handheld devices for various applications.

What should be noted when cleaning and maintaining a refractometer prism?

After each measurement, use clean water or a soft, lint-free wipe to clean off the sample from the prism surface to prevent scratching. Do not allow chemicals or sample solutions to dry on the measuring surface, and always store the device in a dry place.

How to select a suitable refractometer for samples with high viscosity or high fat content?

For dark, high-fat, or highly viscous samples, users should choose specifically designed models to maintain stable measurement signals. Please send your requirements and specific sample details so Hoa Viet can recommend the appropriate model.
