November 19th; Humidity Calibration (part 2)
Because a humidity sensor cannot be protected nermetically, it is exposed to the dirt and chemicals in ambient air or the gas being measured. This exposure may cause drift and, in fact all humidity sensors drift. The process of calibration ensures that the measurement is consistent and within the instrument specifications. Topics covered in part 2 include:
- practical calibration procedures
- reference equipment & saturated salts
- good calibration practice
December 10th; Dewpoint in Compressed Air
Because dewpoint is sensitive to pressure changes, dewpoint is especially relevant regarding the compressed air system. It is imperative that you understand dewpoint and how to make a proper measurement if you are running a compressed air plant. Topics covered in this webinar:
- definition of dewpoint
- pressure and/or temperature effects
- why is dewpoint measurement important in a compressed air system
- where to we measure
- atmospheric and pressure dewpoint

June 4th; How to Choose the Correct Hygrometer?
Choosing the right hygrometer is step #3 in basic humidity good measurement practice. Learn about what you should consider in order to choose the best and correct instrument for your application:
- 10 questions to ask yourself before choosing the hygrometer
- interpreting the manufacturer's specifications
- what to consider when choosing a vendor
August 13th; Good Measurement Practice - Humidity
Good measurement practice in humidity measurement will decrease your uncertainties, increase relibility and improve repeatability. Learn about the 7 points for Good Measurement Practice.
September 24th; Uncertainty versus Accuracy in Humidity Instruments Specifications
There is always some uncertainty associated with any measurement and humidity is no exception. Learn about some basic facts around uncertainty in humidity measurement:
- accuracy, uncertainty, error or precision?
- what factors contribute to uncertainty in humidity measurement?
- type A and type B evaluations
October 22nd; Humidity Calibration (part 1)
Because a humidity sensor cannot be protected nermetically, it is exposed to the dirt and chemicals in ambient air or the gas being measured. This exposure may cause drift and, in fact all humidity sensors drift. The process of calibration ensures that the measurement is consistent and within the instrument specifications. Topics covered in part 1 include:
- why do we calibrate?
- basic definitions; calibration, adjustment and specification
- traceability
- accredited versus non-accredited calibration labs

Who should attend?
Engineers, technicians, managers and anyone with an interest in further understanding of humidity and humidity measurement principles with a desire to make a better measurement of humidity.
What will you learn?
Theory, Terms and Definitions of humidity and all psychrometric parameters. Learn how pressure and temperature do or do not affect the various parameters. Learn about good measurement practice in measurement and calibration.
How will it apply?
As with any proper measurement, the first step towards good measurement practice is to understand the thing you are measuring. By understanding the theory, terms and definitions that quantify humidity, you will be in a better position to diagnose and correct humidity measurement issues and ensure that you are getting repeatable and reliable measurements.
