ERWEKA TBH 325 TD
Similar to the TBH 325 the ERWEKA TBH 325
TD offers the possibility to measure with the
“constant speed” and “constant force” hardness
testing principles. The programme menu may
select the required measurement principle
within seconds.
The TBH 325 TD in addition offers automatic
measurement of sample diameter/length and
semi-automatic measurement of sample thick-
ness. The units’ electronics are linked to a digi-
tal thickness measuring device under which the
sample is placed before testing hardness and
diameter/length. The thickness measuring
gauge is lowered manually and the displayed
result is transferred to either create a 3 parame-
ter print-out or transfer the data to a PC with the
optional MC.net software.
It is possible to select results in N, KP and SC
as well as mm and inch.
Additional features:
 Measuring range for diameter:
up to 26.00 mm
 Measuring range for thickness:
up to 12.00 mm
 Accuracy 1 N; 0.03 mm
 Values in mm or inch

ERWEKA TBH 325 WTD
Semi-automated ERWEKA combination tester
for testing the 4 essential parameters of round
and odd shaped samples (weight, thickness,
diameter and hardness). The TBH 325 WTD is
based on the TBH 325 TD and offers the same
functions (“constant speed” and “constant force”
measurement principle etc.).
In addition an external Sartorius or Mettler ana-
lytical balance with windshield (20.0 mg to
50.0000 g; accuracy 0.1 mg, Sartorius bal-
ance with in-built calibration weight) is con-
nected to the unit. Before testing the other pa-
rameters, the sample is placed manually to the
balance; the weight is determined and trans-
ferred to the units’ electronics.
Standard delivery range without balance; differ-
ent brands and types of balances optionally
available.
Additional features:
 Measuring range for diameter: up to 28.00
mm
 Measuring range for thickness: up to 12.00
mm
 Measuring range for weight (dependant on
balance): 20.0 mg – 50.0000 g
 Accuracy 1N; 0.03 mm; 0.1 mg
 Values in mm or inch, mg or g
