TBH 425 Series


 

The TBH 425 is a tablet hardness and combination testers for automatic measurement of up to 10 samples. The samples are inserted in a star-shaped feeder which automatically transports the samples to the test station. Depending on the model, automatic measurements can be taken for tablet hardness and optional thickness, diameter or length (oblongs) 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 3 individual plus/minus tolerances (T3 = pass/fail criteria) and remarks may be stored for up to 50 different products and recalled for testing. Information such as product name and notes can be entered easily. Stored product data can be transmitted via a SD card or USB stick to other devices of the TBH 325/425 family.

 

Calibration is menu guided and may be performed with either weight stones or the electronic ERWEKA AutoCal 2.0 System. Via a USB printer interface a printer can be connected to print out 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.
