Hardness Tester TH 1050 S

Hardness Tester TH 1050 S+

This hardness tester is equipped with user-interactive software in dialogue mode which enables in the ease of operation as well as it provides protection against invalid entries. The design of the Hardness Tester TH 1050 S+ allows it to perform a continuous automatic run of up to 1-100 tablets and it simultaneously measures the different parameter of the tablets. Armed with a linear displacement method, the user can select the speed from 0.4 to 3.2 mm/sec of this tablet hardness tester.

Fast advance and return movement saves time.Plus/minus Tolerance Limit for Pass/Fail criteria with Star mark for out of limit values.
