Heavy Capacity Weighing
Accuracy is Not Accidental
Even for Rugged Applications
The value of a weighing system is proportional to its accuracy. An out of
specification scale can diminish quality, reduce profits and increase liability.
To ensure accuracy, every scale system must be periodically calibrated.
However, as the capacity of a scale increases, calibration becomes
increasingly more difficult, time consuming and costly.
Achieving the accuracy you need for your weighing processes begins with an
evaluation of the impact of weighing accuracy on your business. Meeting
minimum regulatory accuracy tolerances may not be adequate, as a higher level
of accuracy may yield quality, cost or revenue benefits that by far exceed the
cost of a higher-level calibration.

Results You Can Trust
for All of Your Applications
You expect that your Thermal Analysis instrument is always accurate, you trust the
results are precise and you expect your instrument to deliver reproducible, consistent
results within a given range. However, given the sensitivity and resolution of these
instruments and their sensors, the tough applications they are used in and the heat
differences they have to absorb, this is not just a given.
A periodic calibration determines whether your measurement module is delivering correctly
measured values for a given application – or if it needs adjustment. These calibrations need
to be performed regularly to ensure the precision of your instrument.
Regularly maintained instruments reduce the likelihood of day-to-day measurement errors
and prevent potentially expensive follow-up costs. METTLER TOLEDO offers basic and
extended calibration services that can be adapted to your specific calibration needs.

Weight Calibration
Precise Reference Weights
Yield Precise Results
Calibrated test weights are the base of accurate weighing results. Balances and
scales should always be checked with reference weights you can rely on and trust.
As weights can deteriorate over time due to wear, they need to be periodically
calibrated according to their weight class.
At our 11 accredited mass calibration laboratories around the world, METTLER TOLEDO
cleans and calibrates your weights. Our calibration services include a comprehensive
documentation and reporting of conventional mass correction, uncertainty and
tracebility information in accordance with ISO 17025 requirements.
Regulary calibrated weights
Don’t waste precious time with
test weights that are worn and
no longer accurate. There is
nothing more frustrating than
to find a test weight is out of
tolerance after many months of
use – you even may not know
how long you have been testing
against this inaccurate standard.

Good Measuring Practices
Reliability Throughout the Lifecycle
Go Beyond Calibration
Good Measuring Practices by METTLER TOLEDO is a global program supporting you in laboratory
and production environments with quality assurance recommendations for weighing, pipetting
and chemical analysis.
Every Good Measuring Practices guideline consists of five steps that cover the entire lifecycle of your
instruments. All guidelines start with an evaluation of your measurement processes and an
assessment of their associated risks. Based on this information, you are provided with
straightforward recommendations for selecting, installing, calibrating and operating your devices.
By focusing on your processes and their associated requirements and risks, we provide you with
effective measures to maximize operational security and minimize testing efforts and process risk.
