Checking the spectral resolution with UV6 toluene in hexane and UV9 hexane reference filter (blank), calibrated at wavelengths 265 - 270 nm, slit widths 0.5, 1.0, 1.5, 2.0, 3.0 nm.

All filters with serial number, packed in high-quality storage box with DAkkS calibration certificates, for UV6/UV9 Hellma Analytics calibration certificate. Note: Hellma Analytics calibration certificate (factory calibration. not covered by accreditation!)

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. There is no need to repeatedly prepare and produce calibration solutions, which saves 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 accurate 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.
