Mettler Toledo has developed Good Weighing Practice (GWP) global weighing guidelines for the evaluation, operation and testing of weighing systems.
GWP is a risk-based management programme for weighing systems that reduces measurement errors and ensures regulatory compliance.
With GWP the user can control and test instruments according to the risks associated with a particular process, and can save costs where those risks are comparatively low.
All process-involved laboratory instrumentation requires strict control in order to comply with internal quality requirements and external regulatory standards, and balances used for analytical testing or for manufacturing processes are an important focus for any quality system.
By following GWP, quality managers and laboratory managers can continually ensure that their weighing measurements are reliable and risks are kept to a minimum.
GWP guides users through the entire lifecycle of an instrument, starting with advice on how to choose the right balance for your process needs and regulatory requirements.
During this first evaluation step, particular attention must be paid to process tolerances and the minimum operating weight of the balance.
Mettler Toledo Excellence Plus balances offer solutions for secure and precise weighing and are perfect for meeting these requirements.
All Mettler Toledo Excellence Plus balances are equipped with a complete QM package for full traceability, different user profiles, and secure data collection and handling.
Once a user has selected the right balance for their needs, GWP delivers a Mettler Toledo balance complete with a package including installation, user training, calibration and guidelines for routine operation and testing.
The user receives clear recommendations on how the balance should be tested, what weights should be used and how often tests should be performed.
GWP helps users to maintain the required performance of Mettler Toledo Excellence Plus balances with minimum effort, avoiding measurement errors and ultimately keeping risks and costs to a minimum.
