Product description

The refractometer series are based on the principle that the refractive indices of liquids change when the concentration change. It’s portable, easy, quick and no battery required, easier and more accurate than a traditional hydrymeters, more affordable than a digital meter. It’s a perfect tool for adult or young, home or professional use.

It features high-quality optics with smooth focusing. Its 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 general corrosive liquid. (But we do not recommend measuring these liquids for a long time. The residue should be cleaned immediately after measurement. )

This refractometer is designed for measuring the suger content and specific gravity of liquids. A Brix Refractometer that includes a specific gravity scale. You won’t have to do conversions between Brix and gravity when doing measuring, you’ll get the two index in one time. Best of all, it only requires a few drops of liquid for an accurate reading. No need to lose a whole hydrometer test jar of beer or wine in the process.

Product Features


Dual Scale

Specific Gravity and PPT. With this refractometer you can get the result in two different units at the same time in just one test.

Product Features

ATC Function

This refractometer is equipped with automatic temperature compensation function, minimize the impact of temperature on accuracy.



Comes with every thing you need: a hard case, droppers, a screwdriver, a user manual and a cleaning cloth.

Intended Uses

Intended Uses

For Marine Monitoring

For most sea, the salinty is between 30‰~35‰. So this refractometer is ideal for simple marine monitoring and research.

Intended Uses

For Aquariums Water Monitoring

Ideal for aquariums or marine fishkeeping amateurs, cause they just need to make the salinity of water similar to the sea water.


For Swimming Pool Water Measuring

If you use a salt chlorine machine to disinfect your pool, you should make sure the salinity right first, normally the salinity should be between 3‰~7‰, this refractometer can help.


For Lab or Indurstry Purposes

Ideal for lab and indurstry use for testing salinity solution in the range of 0~100‰.
