- Calibration
  
  We are one of the leading calibration laboratories in Germany and accredited for more than 300 calibration procedures according to DIN EN ISO/IEC 17025:2018.
  Calibration
- Our measured variables
  Our accredited laboratories cover almost all measurands and offer a unique service portfolio.
- On-site calibration
  We calibrate test equipment and measuring points at our customers' sites with professional competence and high-precision equipment.
- Calibration equipment
  With our portable calibrators for temperature, humidity and pressure, calibrations can be carried out regardless of location.
- Test equipment management
  
  We manage your test equipment with the holistic PRIMAS test equipment management solution for compliance with standards and directives.
  Test equipment management
- PRIMAS online & mobile
  The internet-based test equipment management system PRIMAS online supports the assurance of test equipment requirements - even while on the road.
- PRIMAS validated
  PRIMAS validated is a validation-enabled test equipment management system for companies with GxP compliance requirements.
- PRIMAS exchange
  PRIMAS exchange enables automated data transfer of test equipment data between MES/CAQ systems and our data master.
