What Is a Dew Point Meter?

A dew point meter measures the temperature at which water vapor condenses into liquid water within a gas stream. Dew point is the most accurate and widely accepted method for determining moisture content in compressed air, natural gas, hydrogen, and industrial process gases.

Accurate dew point measurement helps organizations:

Prevent pipeline and equipment corrosion
Protect compressors, turbines, and dryers
Improve product quality
Maintain process efficiency
Meet industry compliance requirements
Reduce maintenance costs
Extend equipment life

Frequently Asked Questions

What is the difference between a dew point meter and a humidity sensor?

A dew point meter directly measures moisture content in gases and is typically more accurate for industrial process control. Relative humidity sensors measure saturation percentage and are often used for ambient air monitoring.

What is a good dew point for compressed air?

Typical compressed air systems operate between -20°C and -40°C dew point, while critical applications may require -70°C dew point or lower.

Can dew point meters be used for hydrogen applications?

Yes. COSA XENTAUR dew point analyzers are widely used for hydrogen production, storage, and fuel cell applications.

How often should a dew point sensor be calibrated?

Calibration frequency depends on the application, but HTF™ sensors are designed for low drift and long-term stability, reducing maintenance requirements.
