DAkkS and ISO calibrations

of pressure measurement systems

 
 

Do you have high safety requirements regarding the monitoring of gauge pressure in a cleanroom? Do you require a calibration certificate for your measurement instruments?
Then our ISO calibration service is perfect for you. You can even use an instrument with a superior DAkkS calibration certificate as your own factory standard.

When calibrating your instrument, we comply strictly with the relevant specifications, use traceable references and thus provide transparency for your measurement results. Our own experienced calibration department will be pleased to calibrate your instruments for you.

Overview of our services

 

Overview of services provided by our certified calibration laboratory for pressure measurements in accordance with DIN EN ISO / IEC 17025:

  • Differential pressure transmitters, calibration devices, absolute pressure transmitters and portable pressure gauges
  • Absolute pressures of 0.25 bar to 20 bar in gases (laboratory medium: air or nitrogen)
  • Negative and positive gauge pressures of -10 mbar to 20 bar in gases
    (laboratory medium: air or nitrogen)
  • Issuing of DAkkS and ISO certificates
 

DAkkS calibration procedure

 

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. five to nine points. The number of measurement values and points used in the procedure is adjusted in accordance with the required measurement range and uncertainty.

Example: Measurement in a calibration with a required uncertainty of < 0.1 % of the measurement range. (Procedure A in accordance with DKD–R 6–1) zoom

Adjustment – more than simple calibration

 
Our service team for adjustments

Our laboratory technicians will contact you immediately if they detect a significant deviation from the target value during start-up or after calibration. You then decide whether our service team should adjust the device in-house to ensure that the measured values are completely accurate. Recalibration after the adjustment guarantees that your processes meet the high quality standards you expect. We offer this service exclusively for halstrup-walcher instruments.
