UR24 - User configuration Instrument takes into account typical behaviour for nD % weight/weight nD 16 8 25 33 42 50 1,33 1,38 nD - concentration nD - temperature nD 1,30 1,40 10 20 30 T (°C) 20% in water Default configuration: sucrose solution curves
UR24 - User configuration 1st STEP: at 20°C fixed temperature find the relationship between the concentration and the refraction index. 2nd STEP: at fixed concentration find the relationship between the corrections, you have to add to the 20°C value and the temperature Product sample 3rd STEP: transfer data in the UR24 refractometric unit Termostating Unit
REFRACTION INDEX-CONCENTRATION configuration UR24 - User configuration REFRACTION INDEX-CONCENTRATION configuration Found the relationship between concentration and nD at seven different values of concentration at 20 °C for desired product
TEMPERATURE COMPENSATION configuration UR24 - User configuration TEMPERATURE COMPENSATION configuration Measuring the refractive index at three different concentrations at three different temperatures, insert the errors in temperature table (difference between read values of each concentration at that temperature and at 20°C)
