Digital Refractometer Series Palette

The Palette alpha series is the ultimate compact instrument which is the result of years of proven reliable performance, ease of operation and the functionality of design. An user scale allows the input of the coefficient into the formula (concentration = Brix x coefficient) to display the concentrations according to each type of samples. Three separate user scales can be entered. External light Interference (ELI)-patent pending. When the intense light penetrates the prism of a digital refractometer, the light waves may interfere with the sensor resulting in inaccurate readings.
