Overview

TBH 325

Overview

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).




Overview

Easy calibration

Simple setup

Calibration of the hardness test station is completely menu driven and may be carried out by either weight stones or the electronic ERWEKA AutoCal 2.0 System. If performing by weight stones, the TBH 325 offers a two-point adjustment of which one point is fixed (0 kg) and the second one may be freely selected of the unit’s measurement range.

To assure accurate results of the complete measurement range, ERWEKA recommends setting the second calibration point in the middle of the unit's measurement range, i. e. at 30 kg. On completion of adjustment the accuracy/linearity of the measurement range may be calibrated and documented (by up to three points within the measurement range).


Optional interfaces

Multiple interfaces

Get connected

Via a SD memory card or USB memory stick the laid down product data can be either secured or easily transferred to any other TBH 325/425. The ERWEKA MC.NET software controls the TBH from a PC. In addition, the USB printer interface can be connected to receive a hard-copy documentation with data such as unit serial number, date/time of calibration, date/time of test run as well as individual results and statistics.

The Ethernet LAN interface allows connecting a computer with the optional ERWEKA MC.NET software. In combination with this option the TBH 325 series is 100 % 21 CFR 11 compliant and can be controlled via a PC.

The TBH 325 series is available for measurement of:

  • Hardness - TBH 325
  • Hardness and diameter TBH 325 D
  • Hardness/diameter/thickness TBH 325 TD
  • Hardness/diameter/thickness/weight TBH 325 WTD
