Portable Digital Refractometer NPDR-100

Portable Digital Refractometer NPDR-100

Portable Digital Refractometer NPDR-100 is a light-weight, hand-held instrument that can measure the Refractive Index and the Brix value for any kind of liquids and provides the user with the information regarding the amount of solids (sucrose) dissolved, indicating the level of juice or drink concentration. The microprocessor controlled system gives accurate results. Small amount of sample is required for determination of refractive index of liquids. Easy calibration can be carried out using distilled water.
