Advantages of a DAkkS accredited calibration
- Get a verifiable independent, effective, and accurate calibration of your extrusion plastometer according to a DAkkS accredited calibration procedure.
- Take advantage of the international recognition of the calibration certificate and elevate the level of trust with your customers.
- Increase the acceptance of your products and save costs by reducing or even eliminating the need for retesting in importing countries.
- Reduce the risk of test result errors to a minimum. The professional calibration of your extrusion plastometer is a crucial component in the determination of reliable test results.
