ERWEKA Tablet Hardness Testers and Tablet Combination Testers now offer the choice of testing under "Constant-Speed" as well as "Constant-Force" measurement conditions. While using "Constant-Speed" the test-jaw is moved at a constant speed (adjustable from 0.05 - 3.00 mm/sec.) for breaking, with the "Constant-Force" System the test-jaw, after touching the sample, increases the pressure to the sample linear constantly (adjustable from 10 - 200 N/sec.). The choice of which measurement principle should be used is up to the user and can be selected within seconds using the integrated Adjustment Menu of each Tester.
