Dual-scale digital refractometer with scales for measuring both Brix (to 85) and refractive index (to 1.500). Both the Brix and refractive index scales can be used to measure a nearly unlimited number of fluids. The Palm Abbe PA202 is a dual scale digital refractometer with scales for measuring both Brix and Refractive index. The PA202 measures Brix from 0 to 85 Brix, which is considerably higher than the Brix scale in the PA201. Brix is a measure of sugar concentration but is also used for measuring the concentration of many other fluids such as metalworking fluids, industrial lubricants, and other industrial chemicals. Also included in the PA202 refractometer, is a second scale for measuring the refractive index of a fluid. Refractive index is a physical property of a fluid that is related to the speed at which light passes through it. The denser the solution, the slower light passes through it and the higher the refractive index. The Palm Abbe refractometer is fast, convenient, and easy to use. Simply place a drop or two of fluid in the stainless steel well and press a button. The custom-designed microprocessor delivers a nearly instantaneous readout in degrees Brix. Nonlinear temperature compensation is automatic and insures that fluids read between 0 and 50 C (+32 to 122 F) are measured accurately. Calibration is automatic and does not require the use of special calibration solutions, or tools. The Palm Abbe refractometer automatically calibrates itself to water and is ready to use in seconds. No screws to turn and nothing to adjust.
