Hellma® calibration standard set UV301 for checking the photometric accuracy (235, 257, 313, 350 nm), Dimensions: 48,5 x 12,5 x 12,5 mm

Hellma® calibration standard set UV301 for checking photometric accuracy in the UV range with UV60 potassium dichromate 60 mg/l and UV14 perchloric acid (blank), calibrated at the wavelengths 235, 257, 313, 350 nm with slit width 2 nm, in high-quality storage box with serial numbers and DAkkS calibration certificates

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.
