Product catalog summary
Calibration Overview
Calibration is essential for ensuring accurate measurements in sensitive measurement technology, such as sensor manufacturing. Regular calibration is required for ISO 9001 certification and helps maintain quality standards by preventing defects in processes and products.
Pressure Measurement Services
The calibration laboratory offers services for differential pressure transmitters, absolute pressure transmitters, and portable pressure gauges. It covers absolute pressures from 0.25 bar to 20 bar and gauge pressures from -10 mbar to 20 bar, using air or nitrogen as the medium. DAkkS certificates are issued for these calibrations.
DAkkS and ISO Calibrations
  • DAkkS Calibration: Conducted at critical measurement points, following standard procedures like DKD-R 6-1. It includes uncertainty documentation and is internationally recognized.
  • ISO Factory Calibration: Suitable for auxiliary devices, it does not state uncertainty and is performed using traceable references.
Since 1999, the laboratory has been accredited by DAkkS, ensuring traceability to national standards.
Calibration Procedures
DAkkS calibration involves conditioning the instrument for 24 hours, performing repeated measurements, and documenting all parameters affecting results. The calibration certificate does not have a validity period, and users must ensure timely recalibration. The laboratory offers adjustment services for halstrup-walcher instruments to maintain accuracy.
Calibration Steps and Requirements
Calibration procedures vary based on required uncertainty:
  • Procedure A: Uncertainty < 0.1%, 36 measured values, 9 measurement points.
  • Procedure B: Uncertainty ≥ 0.1% but ≤ 0.6%, 27 measured values, 9 measurement points.
  • Procedure C: Uncertainty > 0.6%, 10 measured values, 5 measurement points.
Calibration costs depend on the required uncertainty.
Advantages of Calibration Services
The laboratory offers flexible, qualified, precise, and fast services, with a broad range of products tailored to specific requirements. Instruments are typically returned within 10 working days, with an express service available on request.

Calibration services Calibration to maintain quality standards To ensure that an instrument provides accurate measurements, regular calibrations are necessary. Calibration means to operate a target-performance comparision using a measuring instrument and a traceable reference. Calibration of instruments is essential in every area where sensitive measurement technology is used, e.g. in the manufacturing of sensors. It is the only way to guarantee quality standards and prevent defects arising in processes and products from the outset. For companies wanting to attain ISO 9001 certification, regular...

Calibration of Pressure Measurement Systems-3

A DAkkS calibration must be performed in accordance with the specified standards. All the parameters which could have a relevant influence on the result must be considered and documented, e.g. room temperature. The instrument being tested must perform repeated measurements at min. 5 to 9 points. The number of measurement values and points used in the procedure is adjusted in accordance with the required measurement range and uncertainty. 1) of the measurement range (Calibration costs depend significantly on the required uncertainty.)
