Better Repeatability after remove human-factor



PSA2000E is widely used for cement, ceramic, medicine, emulsion, dope, dye, padding, chemical products, catalyst, drilling fluid, abrasive, lubricant, braize, cell, germ, food, additive, pesticide, explosive, graphite, photosensitive material, fuel, ink, metal and nonmetal powder, calcium carbonate, kaolin, water-coal-slurry and other powder materials.

Operation Interface:

Operation interface

Run the software, access control systems interface, manually start the sample testing.


Testing analysis interface and report

After completed test, according to requirement to select records, Average result will be calculated, system generate analysis records form. When test in automatic mode, without data processing, the system automatically get analysis report and save the test records after a comprehensive analysis.
