The MISCO PA201 digital Brix refractometer is a valuable instrument for determining the sugar content in fruits, vegetables, juices, beverages, and in wine and beer making. It is also used extensively as a base scale for measuring non-sugar fluids such as, metalworking fluids, lubricants and industrial chemicals. The MISCO Palm Abbe PA201 has a single Brix scale from 0 to 56 Brix. Brix is a measure of sugar concentration, sucrose, to be exact. One degree Brix is the equivalent of 1 gram of sucrose in a 100 gram sucrose solution. Therefore, Brix is actually the percent by weight (% w/w) of sucrose in a solution. The Brix scale is also widely used for many non-sugar applications, such as metalworking fluids, where people are interested in total dissolved solids. In these applications, the known concentrations of reference fluids are measured on a refractometer, relative to the Brix scale, and the relationship between Brix and concentration is graphed. The concentration of future samples can be easily determined by measuring the Brix value of a fluid on a refractometer and using the chart to convert the Brix reading into the required unit of measure. 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. The Palm Abbe refractometer automatically calibrates itself to water and is ready to use in seconds. No more screws to turn and nothing to adjust.
