METTLER TOLEDO WHITE PAPER REVEALS
CALIBRATION AS THE SECRET
Understanding the behavior of your
balance is key to ensuring accurate and
reliable test results. But how can you
ensure your balance is providing the
kind of accuracy that protects your lab’s
reputation? “Calibration: What Is It?” shows
how periodic calibration provides the
answer.
In environmental testing labs, weighing is
an essential step for the analysis of water,
air and soil. Samples are tested on a routine
basis, and often in high numbers, to ensure
that high-quality, timely analytical results
are obtained
Testing according to customer
specifications requires a good
understanding of underlying process
tolerances. If these tolerances are not well-
understood, test-result quality decreases.
Rework can cause the unnecessary waste of
unique sample material. A lab’s reputation
may be at stake.
Calibration can help combat these issues
in day-to-day lab processing. Periodic
calibration helps to ensure:
Quality. A calibration that takes the specific
process into account, as provided by
METTLER TOLEDO’s Accuracy Calibration
Certificate (ACC) in combination with the
Good Weighing PracticeTM (GWP®) Annex,
can ensure airtight measurement quality.
Routine balance testing established by
such a review can also preempt declining
accuracy, allowing appropriate action to be
taken to minimize drift and ensure quality
between calibrations.
Compliance. The ACC process is based on
the globally recognized EURAMET cg-18
calibration guideline. Its modular approach
is designed to fit your testing lab’s specific
needs, and it is also available as a locally-
accredited (ISO17025-compliant) version.
Regardless of calibration type, METTLER
TOLEDO’s white paper “Calibration:
What Is It?” shows how important it is
to accept only calibration results that
disclose measurement uncertainty, which
quantitatively indicates measurement
quality. Without it, balance calibration is
incomplete and inconclusive.
