School: Guides & Resources
Moisture measurement in gases (and air) is a minority subject area and many first time buyers of humidity instruments – dewpoint hygrometers, portable dewpoint hygrometers and other moisture meters in air and gases – even those with excellent technical qualifications, find they are not well prepared to make the right choice of instrument for their application. In our Humidity School, we give you a thorough grounding in definitions, units and measurement methodology to enable you to make the right product choice.
Lesson 1
Theory and
hygrometric units
This document covers the basics and challenges of hygrometry—measuring water vapor in gases. It explains key concepts like water vapor pressure and saturation, and highlights accuracy issues caused by sensor sensitivity, installation, and low dew point conditions.
Lesson 2
Measurement and
sampling problems
This document outlines the challenges of humidity measurement, focusing on sensor sensitivity, installation factors, and performance issues at low dew points.
Lesson 3
Methods of humidity measurement
This article covers various humidity measurement methods, from traditional to modern techniques, highlighting their principles and limitations.
