The STRUCTURIX CERTIFIED DENSTEP is a density step wedge film to verify the calibration of optical transmission densitometers used in the industrial X-ray field.
Each STRUCTURIX CERTIFIED DENSTEP is:
• Packed in a light-tight waterproof package which protects it
against moisture, dust, etc. guaranteeing a shelf life of at least
• Provided with a calibration certificate and a copy of the NIST
certificate S.R.M. 1001
The density values reported, cross referenced by serial number to
the certificate, are traceable to NIST (the United States National
Institute of Standards and Technology) through traceable
calibrations of the instrumentation and procedures in accordance
with our ISO 9001-2000 approved QA system.
