Nowadays more and more enterprise pays attention on color difference of rare earth.The visual method will be too subjective and not accurate, so most companies are more inclined to use color spectrophotometer.Today we use our CS-800 colour measuring instrument to tell you how to measure the color of rare earth.

CS-800 colour measuring instrument adopts D/8 illumination observation geometry and its testing caliber is upward which is more convenient to measure solid materials, pellets, powder materials and pasty materials.


Solid samples (steel plate, clothes) could be put on the testing caliber directly. Pellets (tablets, color master batches), powders(pigments, coffee) and pasty materials (tomato source) can be put in cuvette and then put on the testing caliber.

Step 1. Prepare the target and testing samples. Weight the samples by electronic balance with equal weight, to prevent the measurement error caused by different weights(as shows in figure).

Step 2.Turn on the colour measuring instruments CS-800 and then calibrate it (as show in figure).

Step 3.Press the rare earth into pellet by jack. Because powder rare earth will cause light-leaking situation. Pressing into pellets will avoid the measurement error.

According to the testing result, customer could see the color value of rare earth directly, and color difference value is also on the screen. Comparing with visual method, spectrophotometer has the advantage of objectivity, simple and fast operation, high repeat ability,time saving, labor cost saving and improves efficiency.
