Instruments designed to measure a sample's refractive index or polarization of light; available in benchtop and portable sizes. Includes accessories and replacement parts.
Refractometers measure the change in the angle of light as it enters a transparent liquid or solid substance. Refractometers are commonly used to identify a material, determine its purity, or indicate the amount of a dissolved substance that it contains.
Lists of standard refractive indexes have been published to help users identify specific compounds or materials.
Refractometers also have different scales for specific purposes. For example, the Brix scale is used for measuring the sugar content of jams, marmalades, maple syrup, and honey. Refractometers are available in various Brix scales and may be calibrated specifically for glucose, maltose, fructose, and other sugars.
What Are Refractometers Used for?
Refractometers are used in a variety of industries and applications:
- Laboratory medicine: Used to measure total proteins in blood samples and specific gravity in urine samples
- Gemology: Used to identify gems
- Aquariums: Measure water salinity and specific gravity
- Industry: Measure coolant concentrations
- Homebrewing: Measure fermentable sugars that will be converted to alcohol
Refractometers may be analog or digital and can be found in handheld or benchtop models. Refractometer replacement parts are also available.

Ideal for measuring the salinity and specific gravity of seawater. Atago™ MASTER-S/Millα Salinity Refractometer uses a new material that is durable against salty samples.
Can set measurement temperature internally and measures the refractive index, Brix or concentration of various liquids accurately and speedily. The ATAGO™ RX-5000α Automatic Digital Refractometer has a thermo-module to control temperature, so a constant temperature water bath is not necessary.
Ideal for high concentration samples such as jam, marmalade, jelly, honey. The ATAGO™ Digital Hand-Held Pocket Refractometer, PAL-2 is water resistant (rated at IP65), so cleanup of viscous samples can be done easily by placing the instrument under running water.
Hand-held refractometer. The ATAGO Master-α Refractometer is equipped with ATC and water resistant at the same time.
The ATAGO™ NAR-3T Abbe Refractometer was developed to give improved measuring accuracy and ease of use. This has been achieved by making fundamental improvements to the optical system, utilizing a larger scale, incorporating a high intensity lamp and using a double control knob to give quick and finer control.
For measuring hazardous and unsanitary liquids. The Atago PEN-PRO Digital Hand-held Pen Refractometer allows you to continuously measure almost any sample in the range of 0.0 to 85.0% Brix.
Measures the % water content of honey easily and displays readings digitally. The Atago Pal-22S Digital Hand-Held Pocket Honey Refractometer is comfortable, easy to use, lightweight and compact.
Ideal for simple, quick and easy measurement of refractive index. Atago™ R–5000 Hand-Held Refractometer features a 3-stage switching scale.
The Atago SMART-1 Automatic Refractometer allows you to measure brix, inverted sugar or High Fructose Corn Syrup concentration in a range of 0.00 to 95.00% and with a high accuracy of ±0.05%.
Covers low-concentration Brix values of fruit juices, other food and beverage products as well as chemicals and industrial liquids. The ATAGO™ PR-32α Digital Brix Refractometer is an upgraded model of the PR-32 with improved measurement accuracy based on the new technology development.
Measure samples from multiple fruits and citrus, including grapes, tomatoes, strawberries and wine, using this Pocket Brix-Acidity Meter.
Designed for applications within the chemical, petrochemical, pharmaceutical, flavors and fragrance industries as well as academic research. Bellingham Stanley™ RFM970-T Peltier Temperature Controlled Refractometers feature a wide measuring range and new 7 in. touchscreen user interface.
Easy-to-read, easy-to-hold, and smooth-sampling refractometer. Atago™ MASTER-53M Refractometer is suitable for a wide range of solution sampling.
Designed for liquid sample measurement. Atago™ Abbe NAR-1T Liquid Refractometers feature the Refractive Index Scale and the BRIX scale.
Ideal for measuring beverages. The ATAGO™ RX-5000α-Bev Automatic Digital Refractometer is a redesigned version of the conventional Rx-5000μ. A flat sample stage replaced the sample well to make it easier to wipe off the sample and to allow for a faster and easier clean up. The RX-5000μ-Bev is ideal for measuring beverages and is equipped with all the standard features of the RX-5000μ.
