Information

Controlled atmosphere test facility NPL offers a range of test and calibration services that support the development and use of air quality monitoring equipment. Our controlled atmosphere test facility (CATFAC) provides a circulating stream of air containing controlled concentrations of test gases in which instruments and devices for air quality measurement can be placed. Typically used to test air quality measurements obtained by diffusion tube samplers, this facility can create air mixtures of varying relative humidity, temperature (5 °C to 40 °C) and “wind speed”. Instruments are placed within the system and can be exposed to the controlled environment for hours, days or weeks. B Air quality sensor test facilities NPL has a range of facilities for creating controlled atmospheres for the testing and calibration of the next generation of air quality sensors. These facilities comprise of sealed chambers in which concentrations of pollutants can be controlled from ppm to ppb levels along with relative humidity, temperature and pressure. Using mass flow controllers to deliver gases to these chambers, the conditions can be varied with time to test a range of sensor performance metrics. Using up to 6 chambers in parallel, this facility can provide an ideal solution for performing a matrix of comparative tests and rapid screening of sensor designs. When used with NPL primary reference gases, this provides a fully traceable calibration system with low uncertainties.
National Physical LaboratoryNational Physical Laboratory - Virtual locationProviding confidence in every aspect of environmental monitoring NPL are the National Measurement Laboratory for the UK and have 800 scientists and 400 laboratories across all science disciplines. Environmental monitoring expertise has been developed by NPL over many years and is a critical aspect of the support we deliver nationally and internationally. We ensure our customers are able to monitor gas emissions reliably and comply with evolving environmental regulations. Our high quality, cost-effective pollution monitoring and analysis services are delivered using unique environmental test facilities. We help industry, research organisations, environmental regulators, government and other measurement providers to evaluate instrument performance, demonstrate conformance with industry-standard protocols and validate instruments in the lab and the field. Our emissions, ambient air sampling and analysis services are accredited to ISO 17025 and all our measurements are traceable to UK national standards, providing you with ultimate confidence in data and ensuring compliance with regulatory requirements. Our expertise and innovation eliminates the need for specialist in-house resources and reduces our customers' technical risk. We deliver revenue, cost and time savings for complex technical challenges. Our unique combination of experts and equipment makes us one of the premier environmental measurement facilities in Europe.
