摘要
In a calibration process, at two different pressures P1, P2, but otherwise similar conditions, the corresponding humidities U1, U2 are recorded. From the pressure-humidity relationship, a correction factor, k is calculated for the humidity measurement. U1 (corrected) = U2 - k k = (((P1/P2) x U2) - U1)/((P1/P2) - 1) An Independent claim is also included for an apparatus for the calibration of a sensor (1), having a measurement chamber with a pressure sensor (7) , a gaseous sample input device, and a data recording and computing unit.
