Dew Point
Dew point refers to the temperature at which air or gas becomes fully saturated with water vapour, causing moisture to condense into liquid water or frost. Measuring dew point is critical across industrial processes because unexpected condensation can lead to severe operational issues. Moisture in compressed air lines or process gases can cause equipment corrosion, pipe freezing, product contamination, and costly system downtime. By accurately monitoring dew point, industries ensure air purity, prevent mechanical damage, and maintain product quality in sensitive applications such as pharmaceuticals, food processing, electronics manufacturing, and chemical production.
Why Dew Point matters
Measuring dew point is critical across industrial processes because unexpected condensation can lead to severe operational issues. Moisture in compressed air lines or process gases can cause equipment corrosion, pipe freezing, product contamination, and costly system downtime. By accurately monitoring dew point, industries ensure air purity, prevent mechanical damage, and maintain product quality in sensitive applications such as pharmaceuticals, food processing, electronics manufacturing, and chemical production.
Dew Point Technology
To measure dew point effectively, several advanced sensor technologies are utilised depending on specific operational requirements.
Aluminum oxide sensors are widely employed for continuous trace moisture measurement in dry gases, operating through changes in capacitance as moisture is absorbed into a porous oxide layer.
Chilled mirror hygrometers provide primary reference-standard precision by cooling a metallic mirror until condensation forms, which is then optically detected to determine the exact dew point temperature.
Polymer capacitance sensors offer fast response times, high stability, and excellent resistance to chemical contamination, making them ideal for compressed air systems and industrial drying applications. Integrating precise dew point instrumentation allows facilities to optimise energy efficiency, protect vital infrastructure, and comply with strict quality standards.”

Dew Point Calibrators
Dew point refers to the temperature at which air or gas becomes fully saturated with water vapour, causing moisture to condense into liquid water or frost. Measuring dew point is critical across industrial processes because unexpected condensation can lead to severe operational issues. Moisture in compressed air lines or process gases can cause equipment corrosion, pipe freezing, product contamination, and costly system downtime. It is therefore essential to keep instrumentation used in measuring dew point calibrated to ensure accurate readings.
Dew Point Data Loggers
Dew Point Data Loggers are used for the long-term recording of the dew point.
Dew Point Sensors
Dew point sensors are used in industries to etermine the temperature at which water droplets begin to form. Water damage can affect product quality, plant performance, and materials. The dew point temperature changes depending on the air pressure and the amount of water vapour in the air.
Dew Point Transmitters
Dew Point Transmitters monitor the dew point of your gas or compressed air system ensuring a longer life for your equipment & reduced maintenance costs. The dew point temperature changes depending on the air pressure and the amount of water vapour in the air.
