How to Measure Compressed Air Dew Point

Dew point measurement tells you how dry the compressed air really is, confirming the dryer is doing its job.

What Dew Point Measures

The dew point is the temperature where moisture condenses, so lower values mean drier air.

Measurement Methods

Chilled mirror and capacitive sensors both measure dew point, each suiting different accuracy and budget needs.

Using the Reading

Trend the dew point over time to confirm dryer performance and catch filter or dryer faults early.
