Dew Point and Compressed Air
Dew point temperature is the main indicator for liquid water in a compressed air system. It the dew point temperature is the same as the temperature of the compressed air, water vapor will condense and you will have water in your compressed air lines. Learn more about dew point and how pressure affects the measurement. Understanding dew point will help you prohibit the formation of liquid water. Topics discussed:
- Basic definition of dew point temperature
- Pressure effects on the measurement and the parameter
- ISO classification and dryer types
- Desiccant dryers – improved efficiency with dew point switching
- A practical example of preventing water in air

Traceability – What is it and how to achieve it – It’s not as straight forward a you think.
The majority of regulations (FDA) and quality systems (ISO/IEC 9001, ISO/IEC17025) which reference the requirement of calibration of measurement instruments require traceability of measurements. We often hear the requirement for NIST traceable calibrations.
In this webinar we look at what traceability actually means and what is does not. We will also take a closer look at how traceability is reported on calibration certificates and the key information that is necessary to prove traceability. We’ll cover answers to these common questions:
- How does traceability affect the measurements that we take?
- How can I prove traceability of my measurements?
- How can I ensure that my suppliers are actually providing traceable calibration results?

Interpreting Humidity Instrument Specifications
Selecting the most appropriate instrument for relative humidity measurement is not as simple as comparing the specifications from various manufacturers. The various manufacturers present the data needed to make a determination of overall instrument performance in their own unique format.
- Learn how to interpret the term “Accuracy”. A specification titled “Accuracy” from one manufacturer may not be comparable to the Accuracy specification from a second manufacturer.
- Explore the differences in specification methodologies of several manufactures
- Learn how to apply a methodology that can be used to objectively compare the specified performance of the instruments.
