TBH 125 Tablet Hardness Tester Overview

The TBH 125 is ERWEKA’s range of basic dual-mode (“Constant Speed” and “Constant Force”) tablet hardness testers, offering accuracy, robust design and basic functions. The TBH 125 is operated via a symbol keypad which allows entering the number of samples required for testing.

Results of sample hardness as well as sample diameter and thickness (both optional) are shown on the two bright LED displays and can be printed (incl. date/time) by the standard USB printer interface. The calibration is menu-guided and includes a calibration print-out (3 point calibration, either statically by weight stones or dynamically by AutoCal 2.0) with date and time of performance as well as unit serial number.

The integrated menu allows setting the measurement mode incl. breaking speed-/force increase rate, time/date, sensitivity of the hardness measurement and a break between the tests to remove dust and debris.
