Mit Sicherheit richtig messen
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).
Accredited Calibrations (DAkkS Calibrations) | Factory Calibrations (ISO calibrations) |
Force: 50 N bis 50 kN (guideline: DKD-R 3-3) | Force: up to 200 kN |
Pressure: -1 to 50 bar relative, pneumatic (guideline: DKD-R 6-1) | Pressure: -1 to 50 bar relative, pneumatic |
Pressure: 1 to 700 bar relative, hydraulic (guideline: DKD-R 6-1) | Pressure: 1 to 700 bar relative, hydraulic |
Mass: up to 20 t |
Decision rules and conformity assessments
Standards, specifications and other rules determine whether and in what form measurement uncertainties are included in the assessment of conformity statements.

At Cartesy, you can calibrate a variety of measuring devices for pressure, force and weight from all manufacturers.
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.
The calibration of measuring devices is important for several reasons:
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/safety test test, since 01.01.2025 they are only subject to the calibration obligation. One of the recognition requirements for an safety test operation on the basis of traffic bulletin no. 411-2024 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.

We recommend that you carry out the calibration as soon as possible to have valid, tested measuring equipment in use again.
