The principle of measurement built into the unit is based on proven electronic load cell technology, used in conjunction with a mechanical drive and electronic signal processing.
The MHT-100 is a sophisticated yet portable instrument, which can measure the fracturing/ breaking point of tablets ranging from 2 mm to 28 mm. The unit is battery operated which can easily be used to conduct inprocess testing of multiple simultaneous tablet presses.
The MHT-100 measures the compressive force every hundredth of a second with an accuracy of +/- 0.5% of the full scale and measures and displays the peak force utilized to fracture the sample.
The instrument has an option to measure tablet hardness in N, kN, Kgs, Lbs, or oz. Error messages, which include overloads when the maximum force of the load cell is exceeded, are provided in the LCD screen.
To measure, the tablet is placed on the measuring platform with the aid of 2 precision ground platen jaws. One side is attached to the load cell, while the other is fixed to the mechanical drive. During testing, the manual jaw is driven toward by turning the knob; which moves smoothly and presses the tablet against the fixed jaw. The process continues until the tablet is fractured and the breaking point is registered by the instrument.
The instrument performs a self test upon activation,immediately displaying thereafter a zero to indicate that testing can be begin. A sliding guard has been provided for safety from flying debris during the operation. A collection tray has also been provided to collect broken bits of the tablet after the operation.
