The NPL Trace Water Vapour Facility

This poster describes the NPL Trace Water Vapour Facility: a new facility for generating gravimetrically traceable concentrations of water vapour in nitrogen.

Following validation, the facility has been used for a range of applications, including performance assessment of a range of trace water sensors.

The Trace Water Vapour Facility forms part of a programme of research at NPL into the validation of trace gas measurements.
