Calibration Service

Cartesy is not only one of the leading manufacturers of measurement technology, we also support you as a calibration service provider with our expertise. In our in-house calibration laboratory, we carry out both accredited calibrations in accordance with DIN EN ISO/IEC 17025:2018 (DAkkS) and factory calibrations (ISO calibrations).

Range of Services

Accredited Calibrations (DAkkS Calibrations)

Factory Calibrations (ISO calibrations)

Force: 50 N bis 50 kN (guideline: DKD-R 3-3:2018)

Force: up to 300 kN

Pressure: -1 to 50 bar relative, pneumatic (guideline: DKD-R 6-1:2014)

Pressure: -1 to 50 bar relative, pneumatic

Pressure: 1 to 700 bar relative, hydraulic (guideline: DKD-R 6-1:2014)

Pressure: 1 to 700 bar relative, hydraulic

Mass: up to 30 t

Accredited Calibrations

DAkkS calibrations are only carried out by accredited calibration laboratories and are internationally recognized. They are based on strict standards (DIN EN ISO/IEC 17025) and guidelines to ensure the accuracy and traceability of the measurement results and are audit-proof.

Factory Calibration:

Factory or ISO calibration differs in its requirements from DAkkS calibration: Here, the specifications are defined by the calibration laboratory or company. Of course, all the test equipment we use is also traceable for factory calibration.

At Cartesy, you can calibrate a variety of measuring devices for pressure, force and weight from all manufacturers.

Calibration Service Provider

As a Cartesy customer, you benefit from competent consultation, fast order processing and excellent service from our experts. Put your trust in Cartesy’s expertise! Convince yourself of our manufacturer calibration service.

Calibrating your measuring equipment has never been so easy: book our calibration service conveniently via the Cartesy Shop and our team will contact you immediately to arrange an appointment. Our calibration experts will take care of everything else. If you can only spare your test equipment from your work processes for a short time, we will support you with efficient scheduling and fast processing.

You can also benefit from complete management by our calibration service: We take care of planning, carrying out the calibration and sending the results to you. We are also happy to take on the repair or maintenance of your measuring equipment. Please contact us for more information.


The validity period of a calibration depends on various factors, such as customer specifications, standards specifications, manufacturer specifications, etc. A calibration laboratory only provides recommendations about the calibration interval.

  • Calibration label on the device with calibration certificate number, date, etc.
  • Calibration certificate in PDF format by e-mail when goods are dispatched

The calibration of measuring devices is important for several reasons:

  • Ensure accuracy: Calibrated measuring devices provide reliable and accurate measurement results. This is particularly important to ensure that products meet quality standards and fulfil customer requirements.
  • Ensure comparability: Calibration makes measurement results internationally comparable. This is crucial for companies that operate in global markets and need to ensure that their products and services meet the same standards, regardless of location.
  • Minimize risks: Measuring equipment that is not calibrated can lead to errors and inaccuracies, resulting in faulty products, rejects and potentially legal consequences such as product liability claims. Calibration minimizes these risks.
  • Compliance with regulations and standards: Many industries have regulations and standards that require regular calibration of measuring devices. Compliance with these regulations is important to meet legal requirements and maintain certifications such as ISO 9001.

Overall, the calibration of measuring instruments is crucial to ensure the quality, accuracy and reliability of measurements and thus improve product quality, customer satisfaction and competitiveness.

Calibration is the comparison of measurements of a test device with the values of a more accurate standard according to a documented procedure with the aim of detecting and recording deviations. Compliance with specified tolerances can also be verified. By calibrating test equipment, its function and accuracy are checked and documented in the calibration certificate. Calibration must always be carried out after repairs and maintenance work. The reference measuring devices used must be traceable to national standards.

The accuracy class of a pressure gauge is the tolerance of the display as a percentage of the full scale value.

The difference between a calibration and a verification is that the verification must be carried out by a government agency (verification authority). In some cases, it may also be mandatory. Calibration is the regular checking of measuring devices. This involves the use of a reference measuring device that is traceable, i.e. corresponds to the national standard. Both processes only describe the checking of the display quality, not its correction.

If, when calibrating a device, it is determined that the deviation is too large and is no longer within the specification specified / desired by the customer, the device is re-adjusted. This process of “re-adjustment” is called adjustment.

Every measuring device ages due to mechanical, chemical or thermal stress. As a result, it delivers changing measured values over time. If the device has become inaccurate, this can lead to disruptions in the process flow or even trigger safety risks. This can be detected quickly through calibration.

The difference is that factory calibration only documents the deviation from the reference, while calibration in accordance with ISO 17025 ensures traceability to the national standard. In addition to the deviation, the hysteresis and repeatability are also documented. This is also internationally accepted.

If pressure gauges are used for the main inspection, they are subject to mandatory verification and calibration. One of the recognition requirements since 01.01.2021 for main inspection based on the Traffic Bulletin No. 190-2020 is that the measuring devices used for the functional testing of air brake systems are calibrated by an accredited calibration laboratory in accordance with the standard.

  • Pressure gauges must be verified every 2 years
  • Further information can be found on the homepage of the Bavarian State Office for Weights and Measures
  • Verification label on the device with info “DE – M year”
  • Our outgoing invoice with note of the verification date
  • No separate verification certificate is issued as with calibration
  • Please see the range of services listed above
  • In general: For force measuring devices and pressure gauges (accredited calibration) and for force measuring devices, pressure gauges and wheel load scales (factory calibration)
  • We recommend that you carry out the calibration as soon as possible to have valid, tested measuring equipment in use again.
  • For verification, all verifications due by then must be made up for and paid for at 2-year intervals (e.g. last calibration in 2019 à valid until 2021, re-verification in 2021-2023, then additional new verification from 2024).
