From The Manufacturer
We have been developing and selling this series of instruments for about 10 years, with a very professional team and factory. We've been concentrating to supply constant stable high standard products to customers all over the world. Our products are equipped with high-quality optics and smooth focusing. The main body is made of aluminum alloy. The internal optical lens with high refractive index make up the precision optical system.The instrument is resistant to abrasion and corrosion, can be used to measure the salinity of general corrosive liquid. (But we do not recommend measuring these liquids for a long time. The residue should be cleaned immediately after measurement. )

An Overview On Refractometers
Required by people with a few select, niche hobbies or occupations, a refractometer is a unique tool with particular properties. Because of this, making the best choice can be challenging. Before shopping for a refractometer, considering several factors can help you determine what to look for to select the right tool for your needs.
Industry and application are the first considerations to bear in mind. If you are a professional beekeeper who wants to ascertain the best time to harvest honey, a refractometer designed to measure moisture, Brix (the sugar content of the liquid), and Baume (the density of the honey). Alternatively, if you have a saltwater pool, you will need a refractometer that tests the salinity of the water.
Ease of use is another factor to consider. You will appreciate a lightweight, portable device that you can pick up and carry as needed. And a prism that is easy to clean will provide more accurate results.
Prism material can be important, as well. While glass prisms are the most economical, they are not as durable as sapphire prisms, which are four times harder than glass.
DWYM Fun Fact
In 1869, German physicist and optical scientist Ernst Abbé built the first refractometer. Five years later, he published a booklet discussing the use of prisms and total reflection to measure the refractive index of fluids. Abbé used the device in his work, designing lenses for a German optical manufacturer.
Around the end of WWI, other manufacturers began producing refractometers, which were primarily created for laboratory use.
The Refractometer Buying Guide
- If you prefer a manual instrument, shop for a transmission-style refractometer. With this device, you place a sample on the prism and align it by turning a control knob.
- If you prefer an automatic instrument, shop for a reflection-style refractometer. With this device, you place a sample on the prism and press a button to read the measurements.
- Density is not the only thing that can change the refractive index of a liquid. Temperature can affect it, as well. A high-quality refractometer will feature automatic temperature compensation, sometimes labeled ATC. This feature will provide consistent reports over a range of practical temperatures.
- Look for a dual-scale refractometer. These instruments report results in both Brix and specific gravity units.
