What is dew point in compressed air systems?

Dew point is the temperature at which moisture in compressed air begins to condense into liquid water. Monitoring dew point ensures air quality meets ISO 8573 standards and prevents corrosion and contamination.

Why is dew point monitoring important for compressed air?

Excess moisture in compressed air causes pipe corrosion, product contamination, pneumatic tool damage, and increased energy costs. Dew point sensors help maintain optimal dryer performance.

What dew point range do the WADS 201-204 sensors measure?

The WADS 201-204 series covers a wide dew point measurement range suitable for monitoring refrigerated and desiccant air dryers in industrial compressed air systems.
