Effortless Atmospheric Dew Point Measurement: No Measuring Chamber Required
Direct and reliable determination of the atmospheric dew point without a dedicated measuring chamber
Monitoring atmospheric dew point has always been an essential part of compressed air and gas quality control. Traditionally, this task required complex measuring setups, including dedicated measuring chambers and manual pressure adjustments.
Today, advanced sensor technology makes the process easier and more accurate. With integrated pressure measurement, the atmospheric dew point can be calculated directly within the system, eliminating the need for additional equipment or manual corrections. This ensures reliable results and simplifies continuous air quality monitoring.

Why were atmospheric measuring chambers used in the past?
In earlier setups, a dedicated measuring chamber was used to simulate atmospheric conditions. The system pressure was manually reduced using the measuring chamber to around 1013 mbar to measure the atmospheric dew point accurately. This approach was mainly applied in laboratories and quality control environments.
Key points:
- Required controlled pressure reduction
- Atmospheric Dew point measured under ambient pressure conditions
- Common practice in laboratory and testing setups
- Static pressure reduction
What disadvantages did the method of using a special measuring chamber have?
Although effective, the traditional method had several drawbacks. Fluctuating system or ambient pressures often led to measurement deviations. Manual pressure adjustments were time consuming and required skilled operators. In addition, conversions from pressure dew point to atmospheric dew point were often inaccurate under changing conditions.
Main issues:
- Deviations caused by pressure fluctuations
- Time consuming manual adjustments
- Inaccurate results not reflecting the actual atmospheric dew point
- Required experienced personnel
How does advanced sensor technology work?
Today, SUTO iTEC dew point sensors feature integrated pressure measurement, removing the need for special chambers or manual adjustments. The sensor continuously monitors the system pressure and calculates the atmospheric dew point directly within the process. This ensures accurate results without additional equipment or interruptions.
The combination of precise humidity sensing and real time pressure compensation enables reliable determination of both pressure and atmospheric dew points, delivering consistent results even under changing system conditions.
What is the role of integrated pressure measurement?
The integration of dew point and pressure measurement ensures precise and stable results. It also enables the direct output of pressure-dependent units such as ppm(v), simplifying the measurement process and enhancing overall reliability.
What advantages does this offer in practice?
- Easy integration into existing systems, reducing installation time and complexity
- High measurement stability and accuracy under real operating conditions
- Reliable and repeatable results without additional hardware or special measuring chambers
- Cost savings through the elimination of complicated measuring chambers and reduced maintenance
- Compact and robust design suitable for demanding industrial environments
- Enhanced process control with precise real-time atmospheric dew point data
- Increased efficiency and confidence in system performance, enabling faster troubleshooting and optimization
