Sato Handheld Refractometers for Brix and Salt Concentration
Sato handheld refractometers provide a portable way to check liquid concentration using an optical scale. The range includes seven Brix models for different concentration levels and the SK-200R for salt concentration. Choose the scale and measuring range to match your sample.
Key Features
- Optical scale for direct visual readings.
- Automatic temperature compensation between 10 and 30°C.
- Lightweight handheld construction for routine checks.
- Different Brix ranges for low-, medium- and high-concentration samples.
- Dedicated salt-concentration model for brine applications.

High-sugar samples such as honey, syrup, jam and marmalade. |
| SK-107R / 0187-00 |
45.0–82.0°Brix |
0.5°Brix |
Medium- to high-concentration samples such as corn syrup, jam and marmalade. |
| SK-109R / 0189-00 |
0.0–50.0°Brix |
0.5°Brix |
A wider Brix range for compatible liquids, including selected cloudy samples. |
| SK-200R / 0190-00 |
0.0–28.0% salt concentration |
0.2% |
Brine, including solutions used for marinating or washing fish. |
Minimum scale division describes the spacing between graduations; it is not an accuracy specification. The SK-200R reads salt concentration rather than Brix.
Product Specifications and Dimensions
Understanding Brix Readings
For a sucrose-and-water solution, Brix represents grams of sucrose per 100 grams of solution. Other dissolved substances also affect refractive index, so a Brix reading does not automatically give the actual sugar content or concentration of every liquid.
For cutting fluids, cleaning solutions and other industrial mixtures, use the appropriate conversion factor or concentration relationship for the specific fluid. Confirm sample compatibility before selecting a model.
Choosing the Right Refractometer
- Measurement scale: choose Brix or salt concentration according to the task.
- Expected concentration: select a range that covers normal samples and anticipated variation.
- Scale division: compare the graduations needed to distinguish changes in your process.
- Sample condition: these instruments are not suitable for opaque liquids such as milk. Check suitability even where a model supports selected cloudy fluids.
- Temperature: use within the stated 10–30°C temperature-compensation range and follow the model's sample-handling instructions.
- Reference check: use the reference material and adjustment procedure specified for your model; do not assume all models use distilled water.
