Atago PAL-RI Digital Refractometer (1.3306 to 1.5284 RI)

A refractometer is widely used in the food production industry and is becoming increasingly popular in the beer making process as it provides a quick and easy way to determine the specific gravity before and after the fermentation process. They are useful in maple syrup, honey and sugar production for the quick brix, or sugar content, reading.

 Refractometers have evolved from a simple analog prism to a highly accurate electronic device capable of wide scales of the refractive index, brix or specific gravity. Conversion of one measurement scale to another is a simple calculation of a conversion factor.

This refractometer is designed to be compact and hand-held with a simple measurement procedure. Simply add a few drops of the sample to be tested to the prism surface and hit the start button. After a 3 second test the refractive index reading will scroll across the screen like an electronic ticker.

With a dual display which simultaneously displays the temperature of the sample as well as the refractive index reading. This refractometer requires no external prism and is calibrated with distilled water. Featuring a refractive index range of 1.3306 to 1.5284 to encompass the majority of tests from very low to high.
