Magnetic Tablet for Dynamic Calibration and Periodical Qualification of Tablet hardness Testing Instruments This instrument represents a tool for calibrating and qualifying the hardness range of Pharma Test and other brand tablet hardness testers. The PT-MT3 instrument has an electronically controlled and magnetically held “finger” made of stainless steel and a load cell attached to it. What is a PT-MT3 and why to use it? The finger is held in position by an electromagnet which is always powered with maximum current. The finger is equipped with a electronical load cell which can be calibrated to allow a maximum force of 500N. The strike arm or jaw of the hardness tester makes contact with the load cell at the finger and tries to “break” the finger away from the electromagnet holding it in place. Depending on the force setting, the force required to make this break can be set stepplessly to maximum 500 N. The load cell has to be calibrated against traceable standards to produce a useful series of equivalent tablet break points. The PT-MT3 can be supplied fully certified. The system acts as a type of tablet simulator, which once broken can, unlike real tablets, be reset for the next test. At the end of a test it’s possible to compare the force reading at the tested hardness tester and the actual setting at the PT-MT3, they should match if the hardness tester works well. Also the testing time can be measured, means the time when the strike arm or jaw of the hardness tester hits the load cell at the finger until breakpoint has been detected.
