Humidity – How to Make a Better Measurement

Relative humidity is a difficult measurement and it is a critical measurement for many industries. A better measurement means the measurement is reliable, repeatable, accurate, and precise. Attendees will gain a basic understanding of the science behind the term relative humidity as well as a summary of the pros and cons in choosing measurement technology.

Overview

Relative humidity is a difficult parameter to measure in a reliable and repeatable manner. A reliable measurement is dependent on two key elements: understanding the science and choosing the correct technology for a particular application.

This presentation will cover the basics of the science of humidity with emphasis on the effects of temperature and pressure variations. Temperature variations are the single biggest cause of error in relative humidity measurements. Attendees will learn how to mitigate the error caused by temperature as well as the potential problems that occur when measuring humidity at different pressures.

The second part of the presentation will focus on matching sensor technology to the application. Not only are there pros and cons with each type of technology, but the pros and cons can depend on the environment being measured. Attendees will learn some basic criteria to evaluate when choosing the correct technology for their particular application.

Key Takeaways

  • Understand how temperature and pressure affect humidity measurement and learn how to use that knowledge to make a better measurement
  • Understand why temperature equilibration is the single most significant error causing issue for humidity measurement
  • Learn how pressure variations affect the measurement of some parameters and not others
  • Discover the pros and cons of common sensor technologies
