Tablet Hardness Tester TH 2050S

The 24 Point Carousel automatically measures the essential parameters of the tablets like the thickness, width, length/diameter and hardness. This tablet hardness tester enables the user to test 20 tablets in a single run which is one of the requirements in the Pharmacopeia. The tablet hardness tester has a large non-volatile data storage memory which stores up to 99 methods along with the user results and validation data.

The print reports of the results, program methods and validation or calibration data are all compliant with the GLP specifications. Linear displacement speed can be selected by the user which gives flexibility.
