Calibration operations provide you with a certificate demonstrating the traceability of your standards with respect to the international system of units. The LNE National Metrology Laboratory safeguards the preservation, development and improvement of France's mass unit as well as its transfer to industry.
This calibration operation consists of determining the flow time of a fluid with known kinematic or dynamic viscosity through the cross-section subjected to calibration at a temperature of 23°C. The calibration uncertainty equals ±3%.
