Achieve compliance, cost savings and quality

Calibration determines measurement equipment performance. With routine equipment calibration and adjustment, you can measure safely, ensure compliance and avoid the costs of inaccurate measurements.

Achieve and maintain compliance through consistent procedures and adhere to local and global regulations and standards, such as:

ISO 17025
EURAMET
USP, GLP and GMP
NIST Handbook 44 and OIML
Measuring Instruments Directive (MID)

Calibration in detail
You calibrate a weighing device to understand and document how it performs. You adjust the device to change its behavior. It makes sense that you would not want to change the behavior of a weighing device before you understand how it behaves.

Metrological Test Procedures
These are a series of procedures that test the performance of the measuring device and provide you with a full understanding of its behavior.
Measurement Uncertainty
Enhance your understanding of your equipment with the determined measurement uncertainty—a quantitative representation of the quality of measurements.
Minimum Weight
You could be weighing in a range that is unsafe. The minimum weight is a threshold below which your measurement may not be accurate enough to satisfy your process tolerance.
Reference Standards
All calibration testing is performed with periodically re-certified reference standards to ensure full traceability.
