ERWEKA TBH 525
Semi automated tablet combination tester for
measuring up to 5 parameters (weight, thick-
ness, width, diameter/length and hardness) of
round and oblong shaped samples.
The TBH 525, in standard configuration, comes
with a 20 position magazine to hold samples up
to maximum diameter/length of 26 mm. The
integrated menu allows setting an individual
number of tablets to test for each parameter,
e.g. 20 for weight, 15 for thickness, 10 for width,
diameter/length and hardness.
By an integrated load cell the TBH 525 WTD
measures the weight with a tolerance of ± 0.1
mg. The test station is designed in such way
that always the complete sample will lay on the
weight measurement plate.
Thickness measurement is performed by a
device which assures that a minimum of
weight/force is introduced to the sample to
guarantee precise measurement even of soft
and elastic tablets.
The hardness test station is equipped with a
unique roller-alignment-system:
1. The sample is inserted into the test station in
such way that the width is measured by the
test-jaw
2. The roller system will then turn the oblong
so the length and hardness can be correctly
measured
3. After measurement the rollers will move
back so the broken sample, together with
the dust and debris, is rejected
The design of the test jaw allows that even
small samples in combination with the roller
system can be precisely measured for hard-
ness.
Via the numeric membrane keypad with alpha-
numeric sub function the nominal hardness in
combination with 2 individual plus/minus toler-
ances (T2 = pass/fail criteria) and remarks may
be stored for up to 20 (optional 50) different
products and recalled for testing. Information
such as product name and remarks can be
entered similar to writing a message on a mo-
bile phone.
Stored product data can be transmitted via SD
card or USB stick to other devices of the TBH
325/425 family.
Cleaning of the unit is fast and easy: the maga-
zine is to be removed so the complete transport
way with all test stations to offer easy access to
the transport way and all test station for manual
cleaning.
Calibration is completely menu guided and may
be performed by either weight stones or the
electronic ERWEKA AutoCal 2.0 System.
Via a standard USB interface a printer can be
connected to receive hardcopy documentation.
Alternatively the TBH 525, similar to TBH
225/325/425, via LAN interface, can be inte-
grated into computer network to allow hard
copy documentation at a central network printer
(Win.print software required).
The serial LAN/USB interface allows connecting
a computer with the optional MC.net software
for external control. In combination with this, the
TBH 525 series is 100% 21 CFR 11 compliant.
