Catching the Drift: What your Humidity Measurement Sys.
Catching the Drift: What your Humidity Measurement Sys.
Kevin Bull, CEO, Veriteq Instruments
Humidity affects virtually all measurements. Product quality and efficacy as well as any critical process where environmental parameters must be measured requires that humidity is accurately monitored and recorded. However, despite many advances in measuring other parameters (like temperature, particulates, or voltage) traditional measurement and recording systems for humidity introduce errors that are frequently misunderstood.

One reason for this is that most product specifications for RH instrumentation have understated measurement uncertainties. Knowing what to look for when purchasing RH monitoring equipment can help Calibration Lab, Quality Assurance and Quality Control professionals ask the right questions during the research phase of a purchase. Additionally, understanding how humidity is measured will help professionals optimize their RH monitoring systems based on the specifics of their applications.

This paper will cover the most common uncertainties and sources of error-including sensor drift-in Relative Humidity measurement. The technology of recording and archiving RH data and methods for reducing uncertainties will also be discussed.
