TBH 425

TBH 425

The TBH 425-series are hardness testers for automatic measurement of up to 10 samples. The samples are inserted in a star-shaped feeder which transports the samples from test-station to test-station.

Automatic measurement can be taken for tablet thickness, diameter and hardness of round and odd shaped samples.
An aligment routine for oblong shaped samples as well as a support-groove in the hardness test-station (optional) help to align odd shaped samples while breaking.

Via the numeric membrane keypad with alpha-numeric sub function the nominal hardness in combination with 2 individual plus/minus tolerances (T2 = pass/fail criteria) and remarks may be stored for up to 20 different (optional 50) products and recalled for testing.

Information 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.

Calibration is menu guided and may be performed by either weight stones or the electronic ERWEKA AutoCal 2.0 System. Via a standard USB printer interface a printer can be connected to receive documentation.

The serial LAN/USB interface allows to connect a computer with the optional MC.net software for external control. In combination with this, the TBH 425 series is 100% 21 CFR 11 compliant (see TBH 455e).

The TBH 425 series is available if several versions for measurement of

• hardness  - TBH 425,
• hardness and diameter - TBH 425 D,
• hardness/diameter/thickness - TBH 425 TD,
• hardness/diameter/ thickness/weight  - TBH 425 WTD.
