Use this refractometer to test solutions with a higher sugar content, such as fruit juice concentrates, canned fruits containing added sugar, or ketchup as well as for egg yolk. Place a drop or two of a sample on the prism and read the results. Sper Scientific portable refractometers work in ambient light with no battery or other power source necessary. A refractometer measures the extent to which light is bent (refracted) through a liquid sample. They are commonly used to help identify or confirm the identity of a sample, assess the purity of a sample, or determine the concentration of a solute in a solution. They can be used in labs, on production lines, in the field or anywhere. Simply place a drop or two of a sample on the prism and read the results immediately. With reasonable care their reliability, precision and optical performance will last forever. 5 Year Warranty, RoHS, water-resistant Comes with Hard Carrying Case & Calibration Tool Resolution: 0.2% Accuracy: ±0.2% All Sper Scientific refractometers come complete with: Rubber coated hand grip and construction, which insulate the test solution from inaccuracies caused by the user's body heat.
