ERWEKA TBH 325
The new TBH 325 series is the hardness tester
with integrated product memory for up to 20
products developed for those customers who
require robust design, easy handling and fast
Qualification without complying 21 CFR 11
regulations.
Via the numeric membrane keypad with alpha-
numeric sub function the nominal hardness in
combination with 2 individual plus/minus toler-
ances and remarks may be stored for up to 20
different products and recalled for testing. In-
formation such as product name and remarks
can be entered similar to writing a message on
a mobile phone. Stored product data can be
transmitted via SD card or USB stick to other
devices of the TBH 325/425 family. Since the
samples are inserted into the test station
manually all kind and shapes of samples can be
tested. Calibration is completely menu guided
and may be performed by either weight stones
or the dynamic ERWEKA AutoCal System.
Via a standard USB printer interface a printer
can be connected to receive hard copy docu-
mentation. The serial LAN/USB interface allows
connecting a computer with the optional MC.net
software for external control. In combination
with this, the TBH 325 series is 100% 21 CFR
11 compliant.

ERWEKA TBH 325 D
Similar to the TBH 325, the ERWEKA TBH 325
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 325 the TBH 325 D
measures and documents the sample diame-
ter/length. This also allows you to document
that the sample was placed in the correct
alignment for the hardness testing process.
Additional features:
 Measuring range for diameter:
up to 28.00 mm (Version –D/28) or op-
tional up to 70.00 mm (Version –D/70)
 Accuracy 1 N; 0.03 mm
 Values in mm or inch
