The calibration of manometers or pressure
sensors is performed by direct comparison with a reference.
The generated pressure is measured in parallel on the reference
and on the pressure sensor to be calibrated. The laboratory
has four references available, which are used according
to the type of pressure (differential, relative or absolute)
and the measuring range.
The minimum COFRAC calibration programme is linked to the class of uncertainty of the calibrated instrument (class 1, 2 or 3).
