ERWEKA TBH 225
The new TBH 225 series is the basic hardness
tester developed for those customers who re-
quire robust design, easy handling and fast
Qualification without fulfilling 21 CFR 11 regula-
tions. Since the samples are inserted into the
test station manually all kind and shapes of
samples can be tested.
The unit is handled by a block of numeric mem-
brane keys and the menu displayed at the illu-
minated full graphic LC display (240x64 dots).
Calibration is completely menu guided and may
be performed by either weight stones or the
electronic ERWEKA AutoCal System. Via a
standard USB printer interface a standard or
laser printer (types on request) can be con-
nected to receive hardcopy documentation.
The LAN/USB interface allows connecting a
computer with the optional MC.net software for
external control. In combination with this, the
TBH 225 series is 100% 21 CFR 11 compliant.

ERWEKA TBH 225 D
Similar to the TBH 225, the ERWEKA TBH 225
D offers the possibility to measure with the
“constant speed” and “constant force” hardness
testing principle. The required measurement
principle may be selected by the programme
menu within seconds.
In addition to the basic TBH 225 the TBH 225 D
measures and documents the sample diame-
ter/length. This also allows documenting that
the sample was placed in the correct alignment
for the hardness testing process.
 Measuring range for diameter:
up to 28.00 mm (D/28 Version)
or optional
up to 70.00 mm (D/70 Version)
 Accuracy 1 N; 0.03 mm
 Values in mm or inch
