Digital refractometer CNT95

for the food industrylaboratoryhand-held

Digital brix laboratory refractometer CNT95 is designed to measure the concentration of soluble solids(almost 100% sugar) in aqueous solutions of sugar content of solution such as fruit juice,syrup,puree,ade,coffee drinks,cocoa drinks,soft drinks,water-soluble cutting oil,water-soluble washing solution,etc. Introduction: Digital brix refractometer most operate on the same general critical angle principle as a traditional handheld refractometer. The difference is that light from an LED light source is focused on the underside or a prism element. When a liquid sample is applied to the measuring surface of the prism, some of the light is transmitted through the solution and lost, while the remaining light is reflected onto a linear array of photodiodes creating a shadow line. The refractive index is directly related to the position of the shadow line on the photodiodes. Once the position of the shadow line has been automatically determined by the instrument, the internal software will correlate the position to refractive index, or to another unit of measure related to refractive index, and display a digital readout on an LCD or LED scale.
