BALANCES
MGB Series of microbalances have been
designed to meet the high requirements
of mass measurements with the highest
precision.
Measurement reliability & accuracy is
ensured by internal calibration.
Microbalances consist of two major parts
(an electronic system and a precise
mechanical measurement system in a
separate enclosure). This solution eliminates
the temperature influence and separates
from shocks and vibrations caused by users
operating software.
All the elements of the balance are made
of glass and steel which eliminates the
influence of electrostatics on the weighing
process.
