The new AutoPosition tool (patent pending) >> not only aligns convex shaped oblongs, additionally it moves the tablets against the end point! Therefore the risk of wrong measurement results by either inaccurate manual positioning or turning of the samples is dramatically lowered. The AutoPosition tool is optionally available for all ERWEKA tablet hardness and tablet combinations testers of the TBH 225/255 and TBH 325/355 series.
The TBH 225 series is an ERWEKA hardness- or combination tester series have been developed for those customers who require robust design, easy handling and fast validation without fulfilling 21 CFR 11 regulations (password protected access, Audit Trail etc.). As samples are inserted manually into the test station all kind of samples can be tested. Broken samples are removed from the test station into an acrylic glass disposal container.
Optionally an AutoPosition device with two rollers turning in opposite directions can position shaped samples oblong automatically.
The unit is handled via the numeric membrane keypad.
The standard TBH 225 measures the hardness of samples in a range of 3 – 500 Newton with either “Constant Speed” mode or “Constant Force” mode (switchable). 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).
Calibration of the hardness test station is completely menu guided and may be performed by either weight stones or the electronic ERWEKA AutoCal 2.0 System. If performing by weight stones the TBH 225 series offers a two-point adjustment of which one point is fixed (0 kg) and the second one may be selected free 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 3 points of the measurement range.
The USB printer interface printer (PCL 3 printer language) can be connected to receive a hard-copy documentation of unit serial number, date/time of calibration, date/time of test-run as well as individual results and statistics. Alternatively the TBH 225 can be integrated into a computer network via the Ethernet LAN interface to receive the documentation print-out at virtually any network printer.
The Ethernet LAN interface allows connecting a computer with the optional ERWEKA MC.net Software. In combination with this option the TBH 225 series is 100% 21 CFR 11 compliant.
The TBH 225 series is available for measurement of hardness TBH 225, hardness and diameter TBH 225 D, hardness/diameter/thickness TBH 225 TD, hardness/ diameter/thickness/weight TBH 225 WTD.
