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.
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 are provided by
Dillon/Quality Plus.
