Course overview

Humidity is often a critical measurement. For example, in the export of food there is an increasing risk of products being rejected or spoilt through inadequate humidity control during storage or transit. Humidity is the second most important parameter, after temperature, to be considered in the product cycle. Poor humidity control can lead to poor quality, poor shelf life or weight loss, as well as poor energy usage.

This practical one-day course will introduce you to humidity generation, calibration and measurement, along with the conceptual framework for understanding the various limitations in humidity measurements.

The course is relevant to any personnel who use or check relative humidity, dew point or other hygrometers as part of laboratory testing, plant installation or monitoring and maintenance tasks. Staff involved in accreditation and QA programmes especially, whether raw beginners or experienced, will benefit.

Programme Outline

Topics include

  • Humidity concepts and definitions
  • Methods of humidity measurement
  • Selection and use of hygrometers
  • Humidity generation and standards
  • Calibration and traceability
  • Recommended practices

Presenter Profile

Jeremy Lovell-Smith is head of the Humidity section at the Measurement Standards Laboratory and has worked as a metrologist for nearly 20 years. He was responsible for setting up the humidity standard and is an active member of working groups of the Asia-Pacific Metrology Programme (APMP), the international Consultative Committee on Thermometry (CCT) and the International Association for the Properties of Water and Steam (IAPWS). His research interests include modelling of errors and uncertainties in humidity generators and in dewpoint and relative humidity hygrometers.

Ross Mason has been working in science area for over 30 years. He has developed an extensive network amongst commercial clients with experience in almost all areas of measurement. He is currently working on the instrument development and calibration in both the humidity and contact thermometry areas of MSL.
