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
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 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
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.
The power source is from 4 1.5V (AA) batteries which can work
continuously for 50 hours. The MHT-100 has an automatic
power shut off to conserve power. It is also available with an
optional AC power supply adaptor 220V / 110V AC.
Validation of the intrument can be done using an optional Validation
Kit. Calibration services can be provided the Pharma
Alliance Group or their authorized representatives.
