Universal hardness tester PTB-M

portabletabletmanual

PTB-M is a manual hardness testing instrument for tablets. The instrument is made in strict compliance with the EP and USP Pharmacopoeia. PTB-M is very easy to use. Simply place the sample on the testing platform and rotate the knob manually. The jaw will move and force will be applied to the sample. The force is monitored electronically and displayed at the moment of breakage. Test Procedure The hardness value is displayed on the four digit LED display in either Newton (N), Kilopond (Kp), StrongCobb (Sc) or Pounds (Lb). The units can be changed by the press on one button on the instruments control panel. The instrument is battery operated. A power adapter may also be used and is included in the standard supply scope. The results can be documented by connecting a PT-RP80 report printer to the serial printer port of the PTB-M. Calibration and Validation Using the certified PTB-CAL15 weight set, calibration of PTB-M can be carried out on site and requires only a few minutes. The current USP Pharmacopeia requires the force sensor of a tablet hardness testing instrument to be calibrated periodically over the complete measuring range (or the range used for measuring samples) with a precision of 1N. All Pharma Test tablet hardness testing instrument can be statically calibrated over the complete measuring range by the use of different traceable counterweights.
