Hellma® neutral density glass calibration standard F3 for checking the photometric accuracy (0.5 Abs) in the Vis range , Dimensions: 45 x 12,5 x 12,5 mm

Hellma® neutral density glass calibration standard F3 for checking photometric accuracy (0.5 Abs) in the Vis range, calibrated at the wavelengths 440, 465, 546.1, 590, 635 nm with slit width 1 nm, in high-quality storage box with serial number and DAkkS calibration certificate

Hellma® calibration standards are manufactured 100% in Germany.

Compliant with regulations
Hellma® calibration standards comply with the specifications of quality management
systems and pharmacopoeias 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 accredited by the DAkkS* in accordance with DIN EN ISO/IEC 17025 and are supplied with a DAkkS calibration certificate*.

Traceability
All measurement results of Hellma® calibration standards can be traced back to calibration standards measured by NIST (photometric accuracy) or PTB (Physikalisch-Technische Bundesanstalt) (wavelength accuracy).

Resource-saving and sustainable
Hellma® calibration standards can be reused for years without any problems and remain in use for a long time. The time-consuming preparation and production of calibration solutions is no longer necessary, thus saving resources, the environment and the budget. A sustainable and environmentally friendly alternative!

30-year guarantee
We trust in our quality and you can rely on reliable measurement results!
With regular recalibration - at least every two years - in the Hellma Analytics calibration laboratory, you receive a 30-year manufacturer's guarantee on all Hellma® calibration standards.

*) Note: calibration laboratory accredited by the DAkkS according to DIN EN ISO/IEC 17025. The accreditation is only valid for the scope of accreditation listed in the certificate annex D-K-18752-01-00.
