Hellma® calibration standards are 100% manufactured in Germany.

Compliant: The Hellma® calibration standards comply with the specifications of quality management. systems and pharmacopoeias (e.g. Ph. Eur. and USP) for the highest quality requirements and international comparability of the measurement results.
DAkkS calibration certificate*: Hellma® calibration standards are manufactured in the Hellma Analytics calibration laboratory, which is accredited by DAkkS* according to DIN EN ISO/IEC 17025, and are delivered with a DAkkS calibration certificate*.

Traceability: All measurement results of the Hellma® calibration standards can be traced back to calibration standards measured by the NIST (National Institute of Standards and Technology for Photometric Accuracy) or the PTB (Physikalisch-Technische Bundesanstalt für die Wellenlängengenauigkeit).
Resource-saving and sustainable: Hellma® calibration standards can be easily reused for years and remain in use for a long time. There is no need for repetitive, time-consuming preparation and production of calibration solutions, thus conserving resources, the environment and budget. A sustainable and environmentally friendly alternative!

30-year warranty: We trust in our quality and you can rely on reliable measurement results! If you recalibrate regularly – at least every two years – in the Hellma Analytics calibration laboratory, you will receive a 30-year manufacturer's warranty on all Hellma® calibration standards.
