As is the case for all measuring devices, the reference materials used to calibrate spectrophotometers must also be checked and recertified at regular intervals (see for example ISO 9001 “Control of Monitoring and Measuring Equipment”). This allows you to ensure that you consistently fulfill your inhouse quality requirements and guarantees high levels of accuracy and reliability in your measurements.

You can recertify your UV / Vis reference materials from Hellma as well as UV / Vis reference materials from other manufacturers in the DAkkS accredited* Hellma calibration laboratory according to DIN EN ISO/IEC 17025!

*) The accreditation is valid only for the scope listed in the annex of the accreditation certificate D-K-18752-01-00.
