Metrology for humidity at high temperatures and transient conditions

Short Name: HIT, Project Number: 14IND11
Laboratory heating and drying oven
Humidity measurements at high temperatures and transient conditions

Air humidity directly affects the quality of pharmaceutical and food products during both production and storage processes. Recognising the importance of humidity monitoring to production efficiency, the food and pharmaceutical industries dedicate significant resources to the challenge of improving humidity measurements. Many laboratories across Europe calibrate instruments for measuring humidity, but no appropriate methods and techniques are available for performing calibrations at temperatures above 100 °C or under transient conditions. These dynamic humidity measurements form an integral part of environmental monitoring during the manufacture of many industrial products but no proper methods exist to estimate their uncertainty. This project will significantly improve the speed and accuracy of industrial humidity measurements at temperatures up to 180 °C and under transient conditions. The improved measurement and calibration techniques developed will help increase manufacturing efficiency in European industry and could potentially achieve annual savings of millions of euros across European industries.
