Product Description
The ERWEKA TBH 425 is a tablet hardness and combination tester for semi-automatic measurement of up to 10 samples. The samples are inserted into a star-shaped feeder and then automatically transported to the test station. Depending on the device model, automatic measurement can be performed of tablet hardness and (optionally) tablet thickness, diameter, or length (for oblongs) of round or uneven samples.
An alignment routine and an optional support groove in the hardness testing station help to align irregularly shaped samples during the breaking process. Using the numeric keypad with alphanumeric sub-function, the nominal hardness in combination with three individual plus / minus tolerances (T3 = pass / fail criteria) and other comments for up to 50 different products can be entered, saved and recalled for future tests. Information such as product names and batch numbers can also be easily entered. The stored product data can be transferred to other devices in the TBH 325 / 425 family via SD card or USB stick.
The calibration of the hardness testing station is fully menu-driven and can be carried out using either weight stones or the electronic ERWEKA AutoCal 2.0 system. Using the USB printer interface, a printer can be connected to create a documentation printout. The serial LAN / USB interface enables the connection of a computer with the optional MC.NET software for external control. In combination with this option, the TBH 425 series is 100% 21 CFR 11 compliant.
