The TBH 325 is the ERWEKA hardness or combination tester with integrated product memory for up to 50 products. Its robust design can be easily used in production environments. Via the numeric membrane keypad with alpha-numeric sub-function the nominal hardness in combination with three tolerances can be stored for up to 50 products and afterwards recalled for testing.

Alpha-numeric information such as product name and remarks can be entered into the device by using the alpha-numeric subfunction of the keypad, comparable with writing a message on a mobile phone. In addition, the TBH 325 allows to type in batch/lot numbers numerically or even alpha-numerically before the test run starts. The recorded information and test results can be documented via different options: data can be printed out via a connected printer or transferred to a computer over the LAN interface. Since the samples are manually inserted into the test station, all kind and shapes of tablets can be tested. Broken samples can be removed from the test station into an acrylic glass disposal container.

The TBH 325 measures the hardness of samples in a range of 10-500 Newton with two selectable measuring modes: "Constant Speed" or "Constant Force". The measuring sensitivity (3-40 N) as well as the test speed (0.05-3 mm/sec. or 10-200 N/sec.) can be adjusted. Results are displayed and printed in either Newton (N), Kilopond (KP) or Strong Cobb (SC).
