The DAkkS accredited SPEKTRA Laboratory

Calibration Services

Our DAkkS (successor of DKD) accredited calibration laboratory D-K-15183-01-00 is accredited for the measurands acceleration and sound pressure level as well as for measurement amplifiers according to the international standard DIN EN ISO/IEC 17025.

Using our own CS18 Calibration system, our calibration laboratory is capable of performing calibration with minimum measurement uncertainty for almost any possible application.

On-site calibration

We do also offer on-site calibration services at the customer's location of e. g.:

  1. Vibration test systems
  2. Sensor adjustment systems
  3. Production test stands
  4. Special applications

Why a DAkkS (DIN EN ISO/IEC 17025) calibration?
  1. High reliability of calibration results
  2. Continuously monitored quality management by external auditors
  3. International recognition of the calibration results
  4. Results can be traced back to national and international standards
  5. Calibration in line with applicable regulations and standards

As a result of calibration, a DAkkS calibration certificate (calibration according to DIN EN ISO/IEC 17025) or factory calibration certificate, respectively, will be issued. Calibration certificates issued by an accredited laboratory are recognized internationally in the framework of ISO 9000.

How frequently should you have your equipment calibrated?

This depends largely on your special demands, but we suggest that you should have your quality-relevant measuring equipment calibrated every year.

Our service for you:

  1. All-encompassing consultation free of charge
  2. Calibration tailored to your needs
  3. Cost-free reminder of pending re-calibration every year
