TBH 325 Series


 

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 individual plus/minus tolerances and remarks may be stored for up to 50 different products and recalled for testing.

 

Alpha-numeric information such as product name and remarks can be entered by using the alpha-numeric subfunction comparable with writing a message on a mobile phone. In addition the TBH 325 allows to enter batch (lot) number, ie. numeric or even alpha-numeric just before the test-run has started. The entered information will be documented on the print-out or together with the results stored in the computer. Since the samples are inserted into the test station manually, all kinds of shapes of samples can be tested. Broken samples may be removed from the test station into an acrylic glass disposal container.

 

The TBH 325 measures the hardness of samples in a range of 3 – 500 Newton with either “Constant Speed” or “Constant Force” mode. The sensitivity (3 – 40 N) as well as the test-speed (0.05 – 3.00 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).
