Konformität mit nationalen und internationalen Normen

Measurement according to normative specifications

In analytics, the comparability of measurement results is of central importance. Modern analytical processes are therefore based on specifications and rules laid down in national and international standards.
Standards in measurement technology describe terms, measurement methods and measuring units. Standards also regulate networking functions by standardizing interfaces, communication and secure data transmission. They enable a quality agreement for standards and tolerances. Although not legally binding, normative trade is associated with great legal certainty for the user. It facilitates the selection of devices and thus secures the own processes and product quality.

Density meters are also designed and used in accordance with standards. Standards for measuring density regulate, under the aspect of “best practice”, the environmental conditions and sample preparation as well as measurement tolerances, properties and equipment features of a device or certificates of calibration equipment and testing instruments. Whoever uses density meters according to normative specifications can guarantee that measurements are correct and work according to reproducible procedures.

In order to make it easier for you to choose the right density meter for your application, you will find below an overview of all standards and guidelines that refer to density meters. This is a general overview of the standards. Which normative specifications the different density meter models from A.KRÜSS fulfil your requirements, we will be happy to discuss in a personal consultation. Please feel free to contact us.
