Intended Use
The PMA7500.. or PMA 35.... Series
EX-approved scales from Sartorius meet
all requirements for fast and reliable
paint mixing. The scale housing
is solvent-resistant.
The weighing capacity of the single-range
scales, models PMA7500-X and
PMA7500-X.., is 7,500 g.
The capacity of the dual-range scales,
models PMA7500D-X and
PMA7500D-X.., is 7,500 g and
1,000 g, respectively. Models 35D-X
and 35 D-X000C have a 35-kg
weighing capactiy.
The built-in formulation program lets
you calculate different batch sizes and
measure out any amount as you would
a standard batch. The models that
are equipped with the recalculation
program can quickly recalculate batch
amounts to correct the filling procedure
if a component is overpoured or
underpoured; this saves you having
to make time-consuming calculations.
All models come with a program for
mass unit conversion (toggling between
weight units), as well as a serial data
interface and overload protection.
The PMA scales are ideal for
use as inspection, measuring and test
equipment in quality management
systems.
Built-in application programs
can be used for:
– Measuring in two weight units
– Recalculation
– Calculation
– Initializing the scale automatically
PMA scales meet the highest
requirements on the accuracy and
reliability of weighing results through
the following features:
– Efficient filtering-out of vibration
– Stable and reproducible results
– Excellent readability under any
lighting conditions
– Rugged, durable weighing system
– Approved for use in Category

Conditioning the Scale
Moisture in the air can condense on the surfaces
of a cold scale whenever it is brought into a
substantially warmer place. If you transfer the scale
to a warmer area, make sure to condition it for
about 2 hours at room temperature, leaving it
unplugged from AC power. Afterwards, if you keep
the scale connected to AC power, the continuous
positive difference in temperature between the inside
of the scale and the outside will practically rule out
the effects of moisture condensation.
Seal on Scales Verified for Use in
Legal Metrology in the EU*:
EU legislation requires that a control seal be
affixed to the verified scale. The control
seal consists of a sticker with the “Sartorius” logo.
This seal will be irreparably damaged if you
attempt to remove it. If the seal is broken, the
validity of verification will become void and
you must have your scale re-verified.
* Including the Signatories of the Agreement on
the European Economic Area
