Tablet Hardness Tester TBH 425 Semi-automated hardness & combination tester The tablet hardness tester TBH 425 offers semi-automated measurement of tablet hardness and optional thickness, diameter/ length and weight measurement of round and odd shaped samples. The samples are transported automatically to the test station via the star shaped magazine which holds 10 samples. 100 tablets can be tested in one test run. The TBH 425 provides a memory function for 50 individual products or sample types which stores the nominal hardness in combination with 3 individual plus/minus tolerances. Precise hardness and combination* tester Automated transport of up to 10 samples Constant force and constant speed method selectable Automatic cleaning of the transport way Collection container with splash guard Fast and easy menu guided calibration Numeric keypad with alpha-numeric sub function for entering test parameters, product name, batch number and remarks Memory function for 50 products with 3 tolerances Integrated menu (password protected) for static calibration, settings and documentation printout Measuring units in Newton, Strong Cobb and Kilopond Values in mm, inch, mg or g USB interface for USB memory stick SD Card Slot USB printer interface for documentation of time, date, results and statistics 100% USP/EP/JP compliant Hardness testing with constant force or constant speed method Hardness ■■ The tablet hardness can be measured with either constant speed or constant force principle Diameter ■■ A ridge ensures perfect aligned samples to measure first diameter and then hardness Thickness ■■ Thickness is measured via a motor-driven electronic linear potentiometer Weight ■■ The weight is measured manually with the external balance where weight is determined and the data is transferred to the TBH 425 Magazine for 10 samples with automated sample transport.
