Trust Is Good, Traceability Is Better

为了向世界各地的权威机构和商业伙伴证明温度计和密度计的准确性，您需要国际公认的证据:ISO 17025校准。安东帕尔的ISO 17025校准保证设备溯源到国际单位制(SI)。这种可追溯性是确保度量结果在全球范围内具有可比性和真实性的唯一方法。

The Anton Paar headquarters in Austria as well as subsidiaries in the USA, Mexico, and Brazil have accredited ISO 17025 calibration laboratories. This means calibration certificates can be acquired not just directly with an instrument purchase, but also right in the user’s lab. For density calibrations, the temperature is determined by a traceable thermometer and the density by measuring an ISO 17034-certified standard. To achieve a measurement uncertainty as small as possible, exclusively highly accurate density standards are used, whose densities were determined by hydrostatic weighing.

For temperature, Anton Paar offers comparison calibrations of resistance thermometers from 0°C up to 200°C with an exceptionally small measurement uncertainty of 10 mK. For calibration, Standard Platinum Resistance Thermometers traceable to the International Temperature Scale 1990 (ITS-90) are used. Two temperature fixed points, the water triple point and the melting point of gallium, serve as the primary standards in the lab. Based on different measurement temperatures, new temperature coefficients are calculated in compliance with IEC 60751.
