The WLP-208B average particle size analyzer is an upgraded version of the WLP-202A. Building upon the functionality of the WLP-202 product, it introduces an electronic gravity measurement device. This device can display the applied pressure value in real-time during the compression of powder samples and precisely control the maximum compression force to 22.7kg. This improvement not only enhances measurement accuracy but also effectively avoids experimental errors caused by inconsistent pressure application by different operators.
