Primary standard humidity generators built to order

NPL can specify, design and build world-class primary humidity generators meeting the range and uncertainty required by top national laboratories, or to other specified requirements.

Our humidity generators draw upon NPL's expertise, developed over many years of building primary dew-point and relative humidity standards for the UK and for other national laboratories. They are also equipped with every aspect of supporting instrumentation, software and documented operating procedures. Sub‑chambers for realising relative humidity within a precisely temperature-controlled environment are also offered. Installation, commissioning, complete system validation, uncertainty analysis, user training, measurement audits, and preparation for accreditation can all be provided, if required.
