Secondary standards for calibrating spectrophotometers

With certified calibration standards it's simply measuring with the utmost confidence. In the long run spectrophotometers will only provide correct results if they are calibrated regularly. With liquid and glass filter calibration standards from the accredited Hellma Analytics Calibration Laboratory, the traceability of calibrations carried out to references of the NIST (National Institute of Standards and Technology) is ensured.

Advantages:

- Reliability and comparability of measurement results

- Increase of your quality of work and regulation conformity

- High process transparency

- Simple compliance with quality requirements e.g. ISO 9000, GLP, GMP or the most important Pharmacopoeias (EP, DAB, USP)
