Tablet Hardness Testers
ERWEKA TBH 125
The TBH 125 is a basic dual-mode (“Constant
Speed” and “Constant Force”) tablet hardness
tester for those customers requiring accuracy
and robust design but very basic functions only.
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 (optional) are shown at the two bright
LED displays and can be printed (incl.
date/time) via the standard USB printer inter-
face.
Calibration is menu-guided and includes a cali-
bration print-out (3-value linearity check) with
date and time of performance as well as unit
serial number.
Even at the TBH 125 the integrated menu al-
lows to set the measurement mode incl. break-
ing speed-/force increase rate, time/date, sensi-
tivity of the hardness measurement and a break
between the tests to remove dust and debris.
