Refractometers are highly precise optical instruments whose function is to determine the percentage of soluble solids in a liquid solution, using the principle of total refraction of light (originated by the type and concentration of the substances dissolved in a liquid solution, for example, sugar), which takes place in the boundary layer between the prism and the sample. Therefore, it can be said that the refractometer measures the density of liquids, the denser a liquid the greater the refraction, the more the sugar content, the higher the refraction index. The portable refractometers are simple, resistant and reliable, allowing us to make measurements in the laboratories or outside, with exact measurements of temperatures, refractive index, density pH and color with a small sample, setting aside reliable results, increasing safety and avoiding errors, in addition to reducing costs and improving the operational safety of the laboratory.
This type of refractometer has made these useful instruments evolve with technology. Since it is easier to analyze substances such as lactose, glucose, among others. Its results are accurate, fast and safe. It offers more advantages than the Abbe refractometer, because there is no need for manual annotations, thanks to the incorporation of screens that show the temperatures and the results of each measurement. It also allows to measure several samples with a single refractometer, since it has programming software so that the user has a wide range of scales.
There are two types of refractometers depending on the refractive index detection; transparent systems and reflection systems. Portable refractometers and Abbe refractometers use the transparent systems, while digital refractometers use the reflection systems.

The Kalstein Salinity Refractometer is designed for testing the concentration of salt water and brine and used for quality control in research and clinical laboratories and marine industry. Its scale provides a direct reading of the specific gravity and concentration (part per Thousand) of salt in water. One scale checks the NaCl levels with the range of 0-100 ppt and the other scale gauges Specific Gravity with a range of 1.000 to 1.070. Both enables the direct determination of salinity in water that contains dissolved salt and little or no other dissolved solids. It is suitable for a marine saltwater tank. It’s FULLY EQUIPPED with ATC that automatically adjust itself to correct temperature discrepancies during use
