Certification of Multi-Dimensional Measuring Instruments

Multi-dimensional measuring instruments are used to determine the length, width and height of a rectangular object. If the object is not of the form of a rectangular box, the smallest rectangular parallelepiped box which fully encloses the object is determined*. In the weighing industry, multi-dimensional instruments are often combined with scales to determine the volume order to calculate charges for logistic purposes. The applied principle is simple. Although they have the same weight, a box containing a kilo of lead takes up less space than a box filled with a kilo of feathers. Therefore it will be more expensive to store and ship the box with feathers.

In the last few years, NMi has tested and certified considerably more multi-dimensionals than usual. This increase shows that the market for multi-dimensionals is booming and manufacturers are looking for new markets. If you are in the same situation and if you are looking for an independent certification partner, it is good to know that we have the knowledge and experience to test your instrument according to the Measurement Instruments Directive and the OIML R 129 recommendation. The software in your device will be examined according to the Welmec 7.2 guidelines. Your NMi certificate is accepted by multiple countries and will open doors worldwide for you.
