Get accurate data with calibrated measurement instruments

Take advantage of our calibration technology – for new purchases as well as existing equipment. Regular calibration by Althen ensures that your sensors and testing equipment are working accurately. This is the only way to get meaningful, correct results over the long run. Our experienced experts can correct for deviations and document the results in a calibration certificate. We can support you not only with the calibration of standard sensors and test instruments, but also with special custom solutions.

In-house calibration laboratory for reliable metrology instruments

Unlike other sales companies in the metrology and sensor sector, at Althen you benefit from our in-house calibration laboratory. This is where we test the products we sell and set up our in-house products according to your specifications. For the physical properties of pressure, force and tilt, we can also offercertified factory calibrations according to ISO 9001for sensors and measuring instruments. Measured data are compared exclusively with traceable measuring equipment.

If the sensor is part of a measuring chain, we need the measuring amplifiers belonging to the sensor from you for a professional calibration. If it is not possible to send in the entire measuring chain, we use our own measuring amplifiers for the calibration in our laboratory.

Calibration of Railway Measurement Systems

We offer professional calibrations for

Tools for measuring wheel diameter (FDK, FDK-BT, FDK-124)as well as
Tools for measuring wheel profiles (FDKP-Series)

Testing tailored especially for your sensors and measurement instruments

Custom solutions require custom testing: Besides new purchases and existing equipment we also offer special custom calibration which fits your individual requirements. Benefit from our in-house calibration laboratory: Our experienced experts correct for deviations and document the results in a calibration certificate.

Ensure your measurement accuracy once a year

Be sure measurement deviations are detected and corrected on time. On request, we can regularly inspect your measuring equipment, then repair or adjust it if necessary. That keeps your instruments functional and working reliably for the long term. You can use our service even if your metrology systems are not from our company. Bring your calibration requests to us. We will be happy to advise you and provide you with a custom quotation.

Calibration certificate

A calibration certificate (also calibration certificate or calibration report) certifies the results of control measurements performed under specified conditions. It presents the deviation of the calibration result (deviation and calibration uncertainty) in the form of a calibration function, calibration curve, calibration table or calibration diagram.

The specification of standards enables traceability to national and international standards.

Benefit from:

  • Calibration of individual sensors or entire measuring chains
  • Quality of measurement results
  • Certified factory calibration
  • Traceable calibrations possible
  • Testing according to specifications
  • In-house calibration laboratory
  • Quick delivery
