ISO 17025 Calibration
Trust is good. Traceability is better.
When using or purchasing an Anton Paar instrument, you can trust its accuracy and precision. For internationally recognized proof of this, we offer ISO/IEC 17025 calibration directly from Anton Paar – your accredited partner for temperature and density.
To support our commitment to accuracy, the accredited ISO 17025 laboratories at Anton Paar headquarters in Austria – as well as the Anton Paar USA, Mexico, and Brazil subsidiaries – ensure full traceability to the International System of Units (SI), guaranteeing globally comparable and reliable measurement results.
Protect your instrument with an annual maintenance contract combined with ISO 17025 calibration.

ISO 17025 calibration in Austria (Anton Paar headquarters)
If you are in Europe, you will be issued your certificates from Anton Paar headquarters in Graz. Anton Paar GmbH’s calibration laboratory is accredited by Akkreditierung Austria, a signatory to the ILAC agreements for mutual recognition, ensuring that ISO 17025 calibration certificates are accepted internationally.

The ISO 17025 calibration certificate of an instrument documents the traceability of the measurements to national standards which represent the physical units according to the International System of Units (SI).
Benchtop density meter calibration
Anton Paar calibrates the density and temperature of benchtop density meters according to ISO 17025. The temperature is determined by a traceable thermometer, and the density by measuring a certified standard. To keep measurement uncertainty as low as possible, we exclusively use accurate density standards, the densities of which are determined by hydrostatic weighing.
The measurement result of the calibration is compared with the given reference value of the density standard. Both values, as well as the calculated measurement uncertainty of the calibration, are recorded in the calibration certificate.
Portable density meter calibration
Anton Paar calibrates the density of portable density meters according to ISO 17025 by measuring a certified standard. Calibrations are performed at room temperature.
The measurement result of the calibration is compared with the given reference value of the density standard. Both values, as well as the calculated measurement uncertainty of the calibration, are recorded in the calibration certificate.
Thermometer calibration
Anton Paar GmbH has been an accredited laboratory for temperature calibrations in accordance with the ISO 17025 standard since October 2018. The new temperature laboratory in Graz, Austria, offers traceable comparison calibrations of resistance thermometers from 0 °C to 200 °C and with a measurement uncertainty of 10 mK.
We calibrate your thermometer at different temperatures. If requested, we calculate new temperature coefficients in compliance with IEC 60751 based on the measurement data (i.e., adjustment) and repeat all measurements with the new coefficients.
We calibrate the following temperature probes:
- Pt 100 probe for temperature calibration of DMA/SVM, D = 1.8 mm, L = 350 mm
- Pt 100 probe MPMI, D = 2 mm, L = 300 mm
- Pt 100 probe MPMI, D = 2 mm, L = 500 mm
- Pt 100 probe MPMI, D = 4 mm, L = 300 mm
- Pt 100 probe MPMI, D = 4 mm, L = 500 mm
