How to choose this product

optical-refractometer

An optical refractometer is a portable instrument for measuring the refraction of a solution. This indicates the concentration of one component of the solution via a scale adapted to the sample to be analyzed.

Applications

These devices are used in numerous industries, with different models for the many different food, pharmaceutical or cosmetic products. They also are commonly used to test the sugar content of wine grapes, fresh fruit, juices, etc. Other uses include testing industrial fluids, such as glycol, battery acid and engine coolant.

Technologies

All optical refractometers operate on the same principle. The user places a few drops of sample between the prism and the transparent movable cover slip and looks through the instrument while pointing it toward an external light source. The concentration is read directly against a graduated scale. Many refractometers have zero and temperature adjustments.

How to choose

Choice will depend on intended use, since the sample type will determine the scale characteristics. Thus, manufacturers make instruments for each type of analysis: fruit juices, honey, soup, glycol, coolant, etc.

Advantages

- Reasonable price
- Rapid results

Disadvantages

- Reduced precision
