Linde HiQ accredited calibration gas mixtures

Linde Gas - In an age of global trade, analytical measuring results have to be comparable. This requirement is meanwhile satisfied by a large number of international directives and standards, e.g. DIN EN ISO/IEC 170251. Such regulations call for the metrological traceability of measuring results using certified reference materials as the basis for comparability. Traceability is the possibility of verifying measuring results through calibration with measuring instruments of a known accuracy which are linked to acknowledged measurement standards. In the world of physical metrology, such standard measures are the internationally recognised embodiment of the relevant SI units. These principles form the basis for the analytical results of test and calibration laboratories. Linde calibration gases are distinguished according to the degree of accuracy required. The mixtures are produced in coordinated levels of manufacturing tolerance, measurement uncertainty and traceability. Highly optimised production processes and analysis methods allow us to offer mixtures that accurately match customer requirements in terms of precision while satisfying all definitive norms.
