Calibration of condensation particle counters

We provide confidence in calibration of condensation particle counters (CPCs)

NPL offers an ISO 17025 (UKAS) accredited service for calibration of condensation particle counters against NPL’s primary Faraday cup electrometer (FCE).

Our calibration and measurement capabilities (CMCs) for CPC calibrations have been agreed internationally by the Gas Analysis Working Group of CCQM, in support of the mutual recognition arrangement of the CIPM.  The expanded relative uncertainty of CPC calibrations is typically 5 %.
