How To Use A Refractometer Practical Guide Pdf A refractometer is used to determine the concentration of a substance in solution by measuring how light bends when passing from air into the solution. to use one, place a sample drop on the prism and read the concentration scale where the boundary line intercepts. refractometers come in analog and digital styles and various scales like brix, salinity, or coolant concentration. proper. To make the conversion easier, refractometers are available with scales that are calibrated to read the desired value, in this case, percent salinity. the concentration of a coolant, cleaner, or other aqueous solution is usually determined in the field with the use of a handheld refractometer.
How To Use A Refractometer Practical Guide Linquip To use the refractometer we simply put the sample between illuminating and measuring prisms, use rotating knob to place the shadow boundary on the telescope cross hairs, and ctive index from the scale. liquid samples m damage surface of the prisms. as refractive index changes with temperature for a correct result of refractive index. The simple readout from the scale of refractometer then provides the refractive index directly, or it can be readily determined using a conversion table. the refraction index depends on the wavelength of light, because the speed of light waves in materials depends on their wavelength. If using an analog refractome ter, whenever possible, all samples within a specific field or block should be read by one person, since readings are digital refractometer will usually result in more rapid readings and more accurate data (approximately $300). How to use a refractometer a refractometer measures the angle at which light rays refract “bend” as they move through a gemstone, and provide a reading (refractive index or r.i.) from a scale seen though the eyepiece of the refractometer. because r.i. is unique for each type of stone, it helps to identify many stones.
