Barometric pressure comparison between MIKES and Vaisala: Range from 6 kPa to 130 kPa

Markku Rantanen, Sari Saxholm, Jouni Leskinen

    Research output: Book/ReportReport


    The pressure laboratories of the Centre for Metrology and Accreditation (MIKES) and Vaisala Oyj compared their absolute pressures in the barometric range from 6 kPa to 130 kPa in 2009. Participation in inter-laboratory comparisons is essential for calibration laboratories working with low uncertainties. An interesting point is also the fact that the traceability of MIKES pressure measurements is obtained from dimensional measurements, complemented with pressure measurements at Laboratoire national de métrologie et d’essais (LNE), France, whereas Vaisala pressures are traceable to the National Institute of Standards and Technology (NIST), USA. Two DH Instruments PPC3 pressure controller/calibrators were used as transfer standards. Both instruments were equipped with two absolute pressure ranges: a low range from 0 to 110 kPa and a high range from 0 to 160 kPa. The agreement of the results from MIKES and Vaisala was good.
