Tablet Hardness Tester TH 1050 S

Tablet Hardness Tester (TH 1050 S)

The tablet hardness tester TH 1050S has 12 position carousel which measures the thickness, length/diameter, hardness and width of the tablets automatically. The built-in sweeping blades in the 12 Carousel (TH 1050 S) help in removing the broken pieces, debris and dust of tablets that accumulates during the testing. For the sake of safety, a two-tier method of editing and validation is required to be performed by the admin and the user. Through this tablet hardness tester, it is possible to perform a continuous automatic run of up to 1-99 tablets that helps in saving a considerable amount of time of the researcher
